If you don't find this cool, you have no idea what "cool" really is. You need cool lessons.
As seen at UberCoolStuff , Chris McInnis, Ron LeBlanc and Tom Gwozdz have teamed up to create the world's biggest Katamari controller.
Those of you who are familiar with the Katamari Damacy games understand the bizarre yet addictive premise: Take a big sticky ball and roll up everything you can. So, the three aforementioned guys gutted a Dual Shock 2 controller, used an Arduino microcontroller, grabbed a yoga ball, and created this amazing thing. It was built to be the center-piece of a larger celebration at the Nuit Blanche festival in London. Attendees could play a game of Katamari using a huge building-side projection and the modified yoga ball.
Seriously. Unassailably cool .
