I'm trying to think if there are more ways to take advantage of the iSight camera (besides all the sexual stuff I'm sure we can all think of) . . . .
For example,
Plugging an isight to a mac mini which is connected to your family room 50 inch LCD, so you can talk to your friends or boss like Marty in Back to the Future 2
Security Camera - Motion Detector/Pet Camera
real games of online poker - where a real poker face matters?
that's all i can think of now . . . . more suggestions welcomed!
