Playing Katamari Damacy is always delightful, but I've always wanted a controller that actually emulated the game. Well, now one exists!
With a little bit of elbow grease, a yoga ball, a few optical mice and some other parts, a bunch of crafty Katmari fans made that dream a reality. Sure, things like this have been done before, but it's still amazing.
Also, you can't argue with the adorable smiles of the kids in the video. Those kids are justifiably psyched.
