The graffiti research lab strikes again! And gets me thinking about I/O.
Their project is essentially taking a camera and watching the screen so that they can react to changes. This idea of feedback is pretty powerful. Computers already have both microphones and speakers, but they need cameras to go with their monitors and projectors and they need output devices on their keyboards. Not so we can be all haptic and crazy, but simply for the amazing art that can occur due to these feedback processes. Casting a shadow on a projected screen should change what is output, pointing a laser pointer could place dots for a plinko chip, all of a sudden gestures become THE way of doing things.
All of these things because much easier to program if we stick to the principle that, where there is output, there should be input, and vice versa. Systems get really interesting when they can respond to their own output.
