Surely one of the coolest and craziest robot project I've seen this year.

Buoyant Choreographies by RoMeLa is a fun art project shown at ICRA in Atlanta last year.

It uses special robots made from helium balloons and moving legs that float and walk around. People can play with the robots using touch, game controllers, or even by blowing air.

The robots react by changing colors, moving differently, and showing emotions.
