Rocky Horror Vivification Interfaces

As we continue to look at the interfaces in The Rocky Horror Picture Show, this post will focus on the interfaces used to bring Rocky to life. The fancy Latinate word for this is vivification.

Come up to the lab

The interfaces in the lab where the procedure happens are mounted on an illuminated glass-brick wall. They are heavy and industrial-looking, cased in powder coat red and bolted together. They connect by pipe conduits. It very much reminds me of the ghost containment panel in Ghostbusters, which world be released nine years later.

They include…

We’ll talk about the whole set in a later post, but for now let’s focus on the ones involved in the vivification scene—when Frank-N-Furter brings Rocky to life before the Transylvanian conventioneers. These devices are the Sonic Oscillator, the Reactor Power Input, and the Handwheel.

Screenshot from the movie showing a distance shot of the laboratory interfaces on the wall. Labels in dripping blood type read “Sonic Oscillator”, “Reactor Power Input”, and “Handwheel”. Arrows point from the label to the interface.
This

Throughout the scene, Frank-N-Furter acts as a dramatic ringleader, telling his helpers what to do next. He begins by calling to Riff Raff, who stands at the instrument panel. Frank shouts, “Throw open the switches on the Sonic Oscillator!” Which brings us to…

The Sonic Oscillator

Screenshot from the movie showing Frank at the vat pointing with an intense expression toward Riff Raff. At his side are Columbia and Magneta. Dripping blood typography reads “THROW OPEN THE SWITCHES ON THE SONIC OSCILLATOR”.

This box has two large, vertical lever switches on the left. To the right of the switches is a column with small, dim, cowled displays. (That right half is the Reactor Power Input, to be discussed below.) Riff Raff pulls each of the the levers down, and as he does so, one of the cowled screens illuminate with faint green oscilloscope waves. It has no other discernible effect.

Several critiques about this interface.

  • Up maps more intuitively to on, open, and more. The levers should be pushed up to turn the oscillators on.
  • If they’re critical they remain in an up position for a duration or to prevent accidental activation, it should either latch or the friction joint holding it in place should be very strong.
  • The prop makers were probably constrained to the size of available oscilloscopes, but the screens are quite small compared to their housing. If they are meant to be read at any distance, those screens should be larger, and the displays be reworked to be more legible.
  • These controls are poorly mapped to their actuators. Imagine the improvement: Levers half this height could be stacked on top of the other, and be much more clearly associated with their screens by dint of being adjacent to them and only to them. As it is, when off, the rightmost lever is closest to the screen it does not control.
  • The two levers are quite close to each other. If they are meant to be operated simultaneously, that’s fine, but in the scene Riff Raff operates them separately, so it’s not their only use. If they weren’t stacked to improve their mappings like I suggested above, they should at least be moved apart to decrease the risk of accidental activation.

Three More Triangles!

Next Frank shouts, “And step up the reactor power input three…more…points!

Screenshot from the movie showing Frank pointing dramatically to Riff Raff. Dripping blood typography reads “STEP UP THE REACTOR POWER INPUT THREE… MORE… POINTS!”

The right half of the box has an unlabeled, diamond-shaped dial on top, and, below, a set of eight red triangles arranged in a circle looking a bit like the Umbrella Corporation logo.

(Sorry about the darkness of these images. Keeping the illumination of the buttons visible means I can’t raise the midtone levels, like I could for the prior images.)

At Frank’s command, Riff Raff presses three alternating triangles in the umbrella control. (If numbering like a clock that goes to 8, he presses 5, then 7, then 1.) They illuminate as he presses them. With each button, the needle in the dial steps to the next graduation. Steam begins to escape from the nearby pipes (a side effect, one presumes). Neither the steam nor the reactor power input has any other discernible effect.

Several critiques about this interface.

  • The face should illuminate when the input is above zero for better readability, glanceability, and association with the illuminated buttons.
  • The needle is barely visible, especially from a distance. The needle should be as visible as the glowing buttons.
  • The umbrella-top arrangement of the buttons is poorly mapped. Up maps to more. Right also maps to more in left-to-right reading cultures. This clock wheel arrangement implies circularity, which makes no sense to modify a variable between 0 and 7.
  • Skipping places makes no sense. (The every-other button thing.) Had Frank asked to step it up five or more points, the interaction and display would have been awkward and error prone to both execute and read.
  • Presuming buttons show target value and the dial shows actual value, then they should be tightly mapped. Think of a thermostat where the target temperature is displayed adjacent to the actual temperature. See the comp below for a better suggestion of mapping.
  • If [measurement does not equal target] is an issue, then we need an alert. If the reading exceeds the setting, the setting button should blink; if it falls short, all buttons between the reading and the setting should blink to signal that it the value is not where it should be. Though, I have to note that if that kind of precision is called for, then it shouldn’t be buttons at all, but be a control that offers more precision, like a dial.
  • Riff Raff should just be able to press any button and have it and all the lower value buttons illuminate automatically. Press three, and one and two should illuminate without his having to press them. He shouldn’t have to press all three in sequence. It should also not prevent him from doing so, if he (or Frank) want to be dramatic.
  • Generally speaking, graduations should be labeled. This particular interface has few enough elements that I might give it a pass, since I suspect it can be easily subitized, positively (how many are lit) or negatively (how many are dim).
A comp showing a fan-shaped dial. The glowing fan is divided for 7 graduations. A needle points around 2.8. Above each graduation is a button. The first three are illuminated and glowing. The last four are not. The graphic has the “dripping blood” treatment seen throughout the graphics.

Much better. The comp raises the additional question of how it is turned off. I presume in the original they were toggle buttons that you would press again to turn off, so that could work here. So—press any but the current setting, and it changes. Press the current illuminated setting and the whole thing turns off. If the stakes are high enough, though, Riff might need a separate control or a safeguarded control. We can’t say because we don’t know what this actually does.

Put your hump into it, Riff!

After stepping up the reactor power three… more… points, Riff Raff kneels down to a handwheel, which he cranks clockwise to lower a ceiling-mounted apparatus from high in a cupola to just above the vat.

Screenshot from the movie: Riff Raff turning the handwheel while smiling creepily and looking toward the vat.

This is mechanical, which puts constraints on usability changes. Certainly that grip could be made wider and the axis could be raised to some more ergonomic position. (Or, given what we see on screen, it could be steam-powered and activated by a valve.) But note that, as it is, narratively, this does some things.

  1. It adds to the weight of the scene via the effort heuristic.
  2. It signals that Riff Raff is a servant, having to do difficult manual labor in a humbling position amid steam; which increases the surprise of his later mutiny. (And presages the awesome steam conversation scene in Alien four years later.)

The rainbow soup

The apparatus Riff lowers houses seven colored cylinders of matching-colored, viscous fluid. When they come within reach, Frank-N-Furter turns valves at the bottom of each one to allow the fluids to pour into the vat, turning its contents into a layered, upside-down rainbow.

Manual valves are a fine interface, since it appears precision is not required. This step is more improvisational art than science, it seems.

Aside: Watching this scene carefully I notice that even though the colored fluids are in an inexplicable order in the interface: yellow blue red purple orange blue green (no, I have no idea why there are two blues, maybe one was supposed to be indigo?), Curry takes pains to open them in rainbow order: red orange yellow green blue blue purple. Note this was *not* a reference to the rainbow flag, which goes in the opposite display order and which Gilbert Baker wouldn’t invent until three years after this film was released. It was Curry (or someone on set) paying attention to real-world light spectra.

Anyway, after enough of the fluid has been dropped to create a layered rainbow effect in the vat, Frank-N-Furter frantically closes the valves. (If you’re wondering, editing makes it difficult to tell in what order he closes the valves, but it seems random.) After a beat, Riff Raff cranks the handwheel counterclockwise to lift Rocky—who is gripping the ceiling-mounted apparatus—out of the vat. The rest of the procedure is analog and does not involve technological interfaces, but does involve a musical number in which Rocky is unwrapped like a reverse mummy, while singing.

Screenshot from the movie showing Frank on Riff Raff’s shoulders, gaping in awe at his creation Rocky, as Rocky is being unwrapped and exposing his physique. Dripping blood typography reads “SHA LA LA LA THAT AIN’T NO CRIME”.

That’s it. That’s how Rocky is brought to life. And, now I am happy to declare…

This is the best series of interfaces in the movie

Not for its usability. It’s fairly wretched for that (see lengthy notes above). But…

Diegetically, the unusability is a feature. First, by contributing to the perception to the conventioneers that big, dramatic science is happening before their eyes. It’s impressive theatrics. I think it could go even farther in seeming usable while still maintaining inscrutable complexity, but this does the trick for Transylvanians. Second, it builds on guild mentality. That is, the inscrutability helps deter others from thinking they could easily do it themselves. It’s a kind of job security through obscurity.

Extradiegetically, because the film is partly meant to mock B-movie sci-fi, the fact that they are…

  • poorly designed
  • pseudoscientific at best,
  • cinegenic, and
  • histrionic;

…they are perfect.

No notes.

I mean, 1800-ish words of notes.

But you know, “no notes.”

As if all this drama wasn’t enough. In the next post it’s going to get turned up to 11. Triple Contact Electro Magnet (currently scheduled for 22 Sep 2026)

Rocky Horror Castle Monitors

Probably the most boring of the interfaces in the story (from an interaction design perspective, rather than an ethical one), these are monochrome monitors showing feeds from hidden, closed-circuit television cameras in places around the castle—including places you’d expect to be private.

Screenshot from the movie showing Magenta and Riff Raff looking in on Janet in her room.

Screenshot from the movie showing a monitor with Janet and Rocky in the lab.

Magenta and Columbia watch the laboratory feed from a castle room.

Screenshot from the movie showing Riff Raff delivering the news that Rocky has broken his chains and vanished.

Riff Raff lets Frank-N-Furter know that Rocky has escaped via the monitor in Brad’s room.

Screenshot from the movie showing Riff Raff discovering Dr. Scott outside the castle via the laboratory monitor. The lever is vertical.

Dr. Scott appears at the front of the castle as seen from the laboratory monitor.

The monitors are unusual for being octagonal, but this looks like a frame on a 4:3 television, standard for the mid-1970s. Note that the show that made this treatment much more famous was Battlestar Galactica, which would air 3 years after this movie’s release. (Another potential influence?)

I’ve got to keep control

What on these interfaces can they control? Look above and you’ll see that the monitor in Magenta and Columbia’s room has a single dial in the upper right. We never see it in use.

The one interface we do see in use is the arm to the right of the monitor in the laboratory. It reminds of me of a slot machine arm, but when we see Janet and Riff Raff operate it, they manually pull it down and return it to the upright position. So it lacks the spring-return behavior of slot machine arms. And as we’ll see with the Sonic Oscillator in the vivification post, there are levers on this panel that stay in place. No, it seems to be a loose, positional lever, and the raised and lowered positions do…something…but it’s unclear what.

Such arms would most befit two states, because the extents of the range are easy for a user to achieve. But there are more than two states, even if we just look at the functions in the film.

  1. How to turn it off and on? (We see the laboratory monitor off and on.)
  2. How to change the channel to view other feeds? (The laboratory monitor shows both Janet’s bedroom and the front door feed.)

If this was a real-world interface, we’d additionally want to know…

  1. How to control the volume?
  2. How to control the gain? (For a brighter or darker image, as needed)
  3. How does the camera signal that it is on and recording?
  4. If the cameras can be aimed, how?

I’m sure there are more I’m not thinking of. Two inputs is not enough. It’s easy to imagine the lever delivering a floating point value between 0 and 1, like a volume control, but that doesn’t map to the discrete functions needed for the simplest functions of off/on and channel selection.

50 Ways to Love Your Lever

It’s possible that the arm position is not binary up-or-down but continuous, with angles mapped to meanings, and held positions setting the boundaries of input. Like, pull it 3° and hold for a second and that puts the system in the select-new-channel state. Or maybe each of the Transsexual keyboard keys is mapped to individual angles, like A = 85–90°, B = 80–84°, and so on. The user would have to move it to the right angle and hold it there for a second for that character to be sent to the processor before returning it to 90° as an “ENTER” function. This has historical precedent in the Dial Telegraph by Louis Francois Clement Breguet in the mid-1800s. Pictured below is the sending mechanism for such a system, which gives an idea about how it worked.

An image of the Dial Telegraph as described in the text.

Dial telegraph by Louis Francois Clement Breguet

But note that the usability in the telegraph is provided by a printed guide below the lever that shows what regions map to what letters, so it’s easy to position and confirm that the arm is in the right spot before pressing the commit control. It would be a terrible experience to try and use this without guides or feedback. It would require too much precision and be very error prone.

With no markings on or near the arm, I can’t backworld this into any semblance of sense or usability. Especially since Janet seems to have no problem using it when she encounters the device.

Before anyone comes at me with, “Maybe Transylvanians have more precision and memory and…”, remember we design for humans, and must evaluate interfaces from that POV.

Orientation

I never felt the lever in action, of course, and the prop is almost certainly long since destroyed, but another side note is that… if the lever doesn’t snap in place at the top, and doesn’t have a spring to hold it there, it’s error prone for it to be oriented vertically. Someone could bump it and cause it to fall down, causing some kind of mischief. If it has to be a loose lever, a horizontal orientation of the control would help remove gravity as a complicating factor.

Differentiation of the set of controls is a next concern, and as you’ll read in a later post, I quite like the horizontal orientation of the Triple Contact Electro Magnet lever, which is mounted to the panel just below. Having two horizontal controls, one on top of the other, isn’t great differentiation, even when the control is tightly chunked with its actuator. If it was sticking with this vertical lever for differentiation, then a spring-return lever would make more sense. n.b. It wouldn’t solve the missing controls problem.

A hint of agency?

There is a curious moment when Dr. Scott first appears on the laboratory monitor. The shot is close up on the monitor, so it’s hard to tell if it was due to some action a character took, but the screen goes from staticky to the channel showing Dr. Scott. Many modern systems do that—think of how Zoom automatically switches to the camera showing the current speaker—but it would take a person doing vigilant technical direction back in 1975.

Screenshot from the movie showing Riff Raff discovering Dr. Scott outside the castle via the laboratory monitor. He is speaking and returning the lever to its vertical position.

I’m unprepared to ascribe context awareness to the design of these interfaces, but it would be way ahead of its time if it did. After the close-up shot, a pulled back shot shows Riff Raff returning the lever to vertical. This implies he was there off camera pulling the lever in the first shot, but the film does not show what signal might have had him reaching for it in the first place, or what he did to select the channel where Dr. Scott was shown.

So, in the end, the monitors are a narrative interface, conveying the voyeurism and communication plot moments. Their interfaces are handwaves that enable “character sees thing” beats, and we have to leave them as such.

Maybe we’ll fare better with The Vivification Interfaces

The Rocky Horror Picture Show (1975) — Overview

I’m working on posts about a British horror movie, a Kollywood sci-fi movie, and a post that ties together Chapter 11 of Dungeon Crawler Carl, sci-fi, and Russian Formalist Boris Tomashevsky. I’m also beginning a study on the narrative purposes of interfaces in sci-fi. But all progress has stopped with the news last week that Dolly Parton and Tim Curry have passed.

It’s parasocial, but the feels are real, and it was a lot to bear on top of current systemic anxieties. I’m GenX and both of these entertainers were icons. Parton perhaps even more so because of her extensive humanitarian work, but she only did one sci-fi thing, with negligible interfaces. Curry had a much more extensive filmography to draw from. So to honor him, I thought to review one of his films.

There are a number of sci-fi properties to pick from (Star Wars: The Clone Wars, Earth 2, Captain Planet and the Planeteers, to name a few), but he is probably best known for his outrageous and iconic performance as Dr. Frank-N-Furter from the stage play and subsequent 1975 movie The Rocky Horror Picture Show. That show has a place dear to my heart, so we’re going to review that.

It’s a complicated thing to analyze, but it does have a plot-centric set of interfaces in it, so let’s go. Warning: These are terrible interfaces for real-world modeling. But they weren’t meant to be good, per se, and I feel I have to do something.

Caveats about the summary

Some notes before we begin a plot summary.

  • It’s odd to describe this like it’s some regular cinema experience that you watch, focused on it, from beginning to end. It became a cult classic through decades of live midnight screenings with audience members in costume performing the movie in front of the screen as it’s happening, raucous audience shout-outs “Buy an umbrella!”, and cued events (like water pistols during the Act I rain storm). I’ll describe it straight through, but few ever receive it or remember it this way.
  • It’s a musical and so the flow of events can sometimes be broken by—and sometimes informed by—musical numbers, but these are not called out below unless they are important to the plot. That leaves some of the most memorable things about the film unmentioned, such as the “Time Warp”.
  • The movie is sardonically self-aware, with a narrator and characters breaking the fourth wall, a mix of diegetic and non-diegetic musical numbers, and beats played for comedy rather than for maintaining a believable or consistent internal world. Some of it happily resists diegetic explanation.
  • It’s partly a send-up of B-movie American and British science fiction films of the mid-20th century, so understanding its references and choices depends on being familiar with that sub-genre of movie.
  • Plot is very secondary to camp, flouting taboos, poking fun at trope, musical numbers, and horror.
  • There is a narrator in the film that provides occasional commentary but does not contribute to the plot, so goes unmentioned.
  • This description makes the story seem more coherent than it actually is.
  • I’ll employ my usual neutral tone that I use for summaries, but there is a huge discrepancy between that tone and the vibe on screen.

All that said, it still helps to have this summary on hand if you don’t know the film (or have never bothered to think about it as a narrative) to put its interfaces in something approaching context.

Plot summary

After leaving a wedding in “Home of Happiness” that is Denton, Texas, fiancés Brad and Janet get a flat tire outside a sprawling gothic castle. Together they knock on the door to get some help (for the youth: time was that phones had to be tethered to walls by cords or they could not work, so you had to go to them) only to stumble into a strange convention where an eccentric named Dr. Frank-N-Furter is showcasing the culmination of a scientific project: The vivification of a frankensteined muscle man named Rocky.

Just after Rocky is brought to life, a tough guy on a motorcycle named Eddie breaks out of a Deep Freeze storage room off the main chamber. He has a bloody scar across his forehead. He harasses the guests and hugs Columbia, one of Frank’s helpers, who is Eddie’s lover. Furious that his demonstration was interrupted, Frank-N-Furter grabs a pickaxe and chases Eddie back into the cold storage where he brutally murders him, as Columbia looks on and screams. Afterward Frank-N-Furter finishes his number, and walks Rocky to a makeshift marriage chamber. The scene ends. (Note this summary is a very lossy compression—at this point we’re halfway through the runtime of the movie.)

A frame from the movie showing Frank singing to Rocky how he will make him a man in 7 days.

Brad and Janet are escorted to separate rooms to sleep the night. In disguise, Frank-N-Furter visits each of them in turn and attempts to seduce them, as castle staff watch through monitors. Meanwhile Riff Raff harasses Rocky, scaring him with the flames of a candelabra so much that Rocky escapes his chains and flees through the castle. Riff Raff alerts Frank-N-Furter, still in Brad’s room, mid-seduction.

Janet finds her way to the laboratory where she operates the monitor (why?) and sees Brad and Frank-N-Furter in bed. Jealous and feeling jilted, she finds Rocky herself and seduces him, as Columbia and Magenta watch from a monitor in another room. Frank-N-Furter, Brad, and Riff Raff enter the laboratory and Rocky and Janet hide in the laboratory vat in which Rocky was animated. On the monitor, they see a figure approach the front door and enter in search of something.

Brad remarks that the figure is Dr. Scott, his old science teacher and friend. Frank-N-Furter tells Brad that Dr. Scott works for a department in the Federal Bureau of Investigation looking into aliens (yes, kind of an early XFiles.)

A frame from the movie showing Frank-N-Furter incredulously listening to Brad explain that Dr. Scott is at the castle door. Riff Raff looks on nonplussed.

Frank-N-Furter heads to the instrument panel and operates a Triple Contact Electro Magnet that pulls Dr. Scott’s wheelchair up the stairs, through multiple rooms and hallways, and to the instrument panel. In their confrontation several things are revealed.

  • Frank-N-Furter learns that Brad and Dr. Scott know each other
  • Dr. Scott came to the castle to find his missing nephew Eddie
  • Frank-N-Furter expresses paranoid concerns that Brad was doing reconnaissance for Dr. Scott
  • Janet and Rocky are discovered hiding and their tryst exposed

The scene ends with Magenta sounding a dinner gong and Frank-N-Furter saying that formal dress to the dinner party is optional. (At no point prior to this was a dinner party mentioned.)

During the meal, Dr. Scott reveals that he received a letter from Eddie written in blood reading, “I’M OUT OF MY HED. [sic] O HURRY OR I MAY BE DEAD! THEY MUSN’T CARRY OUT THEIR EVIL DEEDS. LOVE, EDDIE.” In response, Frank-N-Furter reveals with a pull of the tablecloth that they have been eating meat from Eddie’s corpse, which has been sadistically placed in an open coffin beneath the glass dining table. Screaming in fear, Janet runs to Rocky’s arms, which infuriates Frank-N-Furter. He slaps Janet and chases her around the castle with others in pursuit.

A close-up of a handwritten note with red ink, crumpled and partially unfolded, held by a person's hands. The note contains urgent messages indicating distress and a plea for help.

They wind up back in the laboratory where Frank-N-Furter activates a Sonic Transducer, which immobilizes Janet, Brad, and Dr. Scott. Then he has Magenta activate the Medusa, which turns each of them to stone and somehow simultaneously evaporates their clothing. Columbia picks this moment to confront Frank-N-Furter, explaining that she loved him until he dumped her. She insists that he choose between her and Rocky. Unbothered, Frank-N-Furter has Magenta Medusa her and Rocky to stone, as well. We then learn that Frank-N-Furter had taken half of Eddie’s brain to supply Rocky.

A frame from the movie showing Frank-N-Furter, Rocky, Columbia, Janet, and Brad performing a song and dancer number on stage.

As part of a “floor show” (the purpose of which is never explained) Frank-N-Furter dresses the stone characters in drag and makeup and places them on a proscenium stage where someone uses a backstage de-Medusa to un-stone them. In this state they confess through song that they have enjoyed the freedom offered by decadence. Frank-N-Furter appears on stage with them and sings a song valorizing hedonism and committing to one’s deepest desires. The closing of the number reveals a swimming pool hidden beneath the stage in which they all writhe together.

A frame from the movie showing Riff Raff and Magenta in full Transsexual (the planet) drag. Riff Raff aims his anti-matter trident at Frank-N-Furter menacingly.

The song is interrupted by Riff Raff and Magenta, wearing alien uniforms and sporting new hairdos. Riff Raff aims a three-pronged antimatter weapon at them, and announces that the tables have turned: Frank-N-Furter’s mission has failed. He takes control of the mission, proclaims Frank-N-Furter his prisoner, and begins the process of returning their castle to their home planet of Transsexual in the galaxy Transylvania.

Before they leave, Frank-N-Furter sings a wistful song about going home. (Which is achingly poignant, given his recent passing.) Riff Raff tells Frank-N-Furter that he won’t be returning home but will be killed instead. He shoots Columbia, and then Frank-N-Furter. Rocky grabs Frank-N-Furter’s body and tries to flee up the set, but reaching the top, he is overcome by more antimatter beams and falls with Frank-N-Furter’s body into the pool.

Riff Raff gives the humans just enough time to escape the castle before it takes off into the sky beneath a rainbow that appears in the sky just for the occasion.


Again, please attend the caveats listed above. The summary complete, we can begin to look at the interfaces.

This is for you, Tim, and for everyone who made this film what it is today.
