Recompose, the latest piece of technological innovation to come out of MIT's Media Labs, is in many ways unclassifiable. It's a user interface whose design part gesture-based, part touch-based and entirely ambiguous in its purpose. Still though, it's intriguing.
Each tile in the array is powered by an actuator. You can interact with the tiles directly, or you can wave your hands around, not unlike a puppeteer, and the tiles will rise and fall appropriately. Further more, it can also serve as an output device, providing representations of maps or data points. But the real magic of Recompose is comes through in the video. Stop reading and just click play.
