I had another idea!!!
Raise money for awareness WHILE free funding for you. Have hashtags that tweet it up the speed by 5% for 5 seconds
and then have people donate to change the color of an LED underneath and label their cause on the webcam feed.
this could be a viral explosion that will engulf the internet in one day, disappear in the other, and the only winners are the creators and the charities!
If you get child's play charity behind it, you know Peny Arcade will talk about it, and engadget loves these kinds of projects. Be prepared to have to force a shut down from a perceived DDoS attack.
