This is 'I've Fallen And I Can't Get Up', an animation created by Dave Fothergill testing a new crowd dynamics feature that causes characters to flail and struggle after getting knocked down. I don't know about you, but if the Giant Spinning Metal Bar Of Death were a ride at an amusement park, I would ride it. AND keep my hands raised over my head the whole time. At least until they're ripped off. What can I say, I'm a thrill-seeker. I tried pitching a Wal-Mart style Black Friday Trampling ride to Disney but they weren't interested. Your loss, Walt, those tea cups aren't going to keep people visiting forever.
Keep going for the video.
Thanks to The Golden Ninja, who's easy to to pick out in a crowd of regular ninjas.
