Custom-built Katamari controller is made from yoga ball, DualShock 2 pad, power of the cosmos (video)
Conventional wisdom would suggest that making a for-real Katamari Damacy ball would be tricky, but that didn't stop Chris McInnis, Ron LeBlanc and Tom Gwozdz from taking up the challenge. As part of the Nuit Blanche festival in London, Canada (which also included some building-projected gaming), they were able to fashion their very own Katamari ball from a yoga ball, some stickers, wood, an Arduino microcontroller, several optical mice and a dissected DualShock 2 controller. See how it steers after the break.
