What do you get when you invite a bunch of hackers for a few days of creating fun things? How about a human-sized hamster wheel that powers a text message printer?
The cool creation by 1.21 Jigawatts (presumably a Back to the Future fan) from Minneapolis, MN, won first prize of the 2011 Red Bull Creation Brooklyn.
CoolThings blog has the photos of the winner and lots more creations - Thanks Sunny!
