Giant, rolling Katamari Damacy controller

Chris sez, "I am completely obsessed with the Katamari games, so I rounded up a team to throw a Katamari party featuring a 36" Katamari controller controlling the game projected up on a wall. It was a crazy-cool party!"

Yes, yes it was. Next step, a version of this based on an inflatable ball that grows or shrinks in proportion to your katamari's size.
