The built in iSight in Apple's iMac can see infrared light!

While playing around with our new iMac I discovered that the built in iSight can see infrared light for example from the Apple Remote that comes with it. Or any remote for that matter. Take a look at a video here and a larger picture here.

Edit: Well, it turns out that most cameras can see IR as said in the comments. My Canon IXUS 700 can. I'd never noticed that before…
