This is a patented square bounce back cube, Q-BLE. lt looks like a square cube but bounces like a ball,one bouncy ball inside.

You won't have to follow this bouncing ball too far -- being square, it can't roll away. Yet Q-BLE defies geometry by rebounding just as if it were round. The secret lies inside that cube of soft polyurethane foam, where a conventional round rubber ball lurks. Bounce Q-BLE hard enough and its corners compress, letting the round ball inside do the work. When it bounces, the cube spins, producing a strobelike visual effect not found with your everyday sphere. Q-BLE measures two inches square and comes in three Day-Glo color combinations
