This is really cool! I don't think I'd have the bravery to reveal my brainchild to a big company... I'd be way too afraid of the company "stealing" the idea and booting me from my own project or something. But maybe I'm just paranoid and because I've had too many bad experiences with companies and coworkers (particularly supervisors) throwing me under the bus and taking credit for things when I try to contribute a creative idea.
