How cool is this: a cube-shaped multimedia player that accommodates 3-D space and senses gestures at a distance? It's definitely cool, but you know what would make it better? If it actually existed.

For now, the Gesture Cube is just a big old serving of vaporware. But we imagine a time in the not-too-distant future when we can wave our arms in front of it to play the new Lil Wayne record and do the chicken dance to launch Firefox.

We understand that you need to drum up general interest in unproven tech to get funding, but if you're going to tease us, can you at least give the thing a jetpack, too?
