I wanted to build a public database of mechanics and motion. Using some web-based 3d modelling script like Copperlicht and (unknwown magic) I would set up a wiki like site with some standard human and machine models and people could add animations for those models, like martial arts moves, or dance moves, or... whatever.

It's either a stupid idea or a brilliant multimillion dollar idea for someone who isn't working off of their mother's old Dell.
