Totally useless crap that'd be totally awesome to have.

360 Puzzle Sphere

This thing looks like it is a ripoff of a Hasbro game, the Superplexus, which never sold. The game had some kind of embedded electronics for scorekeeping (which sounds even more awesome than this device), but it seems to be long gone from any store shelf. This thing still looks pretty awesome though.
