Fly on the wall
Using Flash, Arduino, and a potentiometer.
Here you can see how the potentiometer is used to scroll through the flash video, so that the viewer controls what they see. If anyone has questions about using flash, I can answer animation issues, but I'm not to familiar with the technical issues of connecting arduino with flash. But if you're interested, feel free to contact me. I'd be willing to help people out with flash animations if they ever need it.
