You guys are ANAL
Dont you have anything better to do? Good GRIEF! These people from Pixar were playing around! God. It was just a pet project to have some fun with the new iMac. What a joke. "This want made by the REAL PROS at Pixar" you said. Good God man. No, wait, you're totally right- they didnt have 300 of their employees working around the clock for 4 years to produce this, like they did for Toy Story and Monsters Inc.
IT WAS A PET PROJECT FOR FUN. Leave it at that. They probably spent an afternoon on it, on a slow day. Dont forget, they have a sense of humor just like everyone else, and big stuidios are always making stuff 'on the side' so they can learn, have fun, and yes, play around. I made iBoing (link on signature) in an afternoon, and Im not Pixar, just a normal guy with some 3d knowledge.
Good grief. Dont dissect it like its the biggest secret in the world.
