One of Griff Tannan’’s gang, named Data, wears a sound board on his vest. When Tannan gets a rise out of Marty by asking if he’’s “chicken,” the gang member underscores the accusation by removing a protective plate over some buttons on his vest and holds one down to play a looping sound clip of a clucking chicken.

That’s pretty awesome, actually. Having all the sounds available at the touch of a button adds a layer of remix culture expressiveness with maximum speed. No modes, no menus, just remembering which sound goes with which button, and his spatial memory is perfect for that. If the buttons were labeled with the sound, or shaped informatively, it might reduce the burden on memory.

You might also reduce the time it takes to respond by removing the protective plate, but Griff is enough of a loose cannon that he might go violent if an accidental sound effect insulted him. So that extra step is probably the safest.

But if we were to really make this it’s most awesome, you’d make it agentive, such that the plate constantly listened to the conversation for keywords or keyphrases and responded with appropriate snarky sound effects. (Smartphone startup founded around this idea in 3…2…1…)
