There are a lot of good reasons to create animations: to impress FIRST judges, to help with team "marketing", maybe create a
public service announcement for your local TV station, or just for the joy of learning.
But contests really motivate us. Lindbergh flew across the Atlantic for the Orteig Prize. Scaled Composites, the first private company to launch a man into space, did it to win the X-Prize. How exciting would it be to build a robot if you weren't competing against other very tough teams?
I see on the
3D Animation forum Team 116 is organizing a contest. That's awesome, but others might also want to help out.
