Tablets may be cool now, but my money is that the Gesture Cube will be the next big thing. The Gesture Cube is basically a touchscreen cube that you don’t have to touch.
The Gesture Cube detects three-dimensional movement. Just wave your hand near it and it’ll detect your movements. It can sync with nearby devices as well. The Gesture Cube also looks very neat. Check out the video for a demo below. Tablets, beware.
