Out!
Hey man that shot was in!
No way buddy, that didn’t even touch the line.
Ugh, okay let’s do it over.

Game on! 

Ever wish you could rewind that last play and remove the frustration of playing it over? It happens to me all the time when I play table tennis, tennis, and handball without a line judge. It looks like ZeroN — a Levitated Interaction Element project from the MIT Media Lab Tangible Media Group can one day make a real world rewind and many other zero gravity applications possible. In the demo video below they defy gravity and digitally control a real world sphere. Obviously the applications extend beyond sphere related sport replays but you have to admit it would be a cool feature for that office ping pong table. 

What if materials could defy gravity, so that we could leave them suspended in mid-air? ZeroN is a physical and digital interaction element that floats and moves in space by computer-controlled magnetic levitation.
