I just got a big gorgeous 20" iMac anmd haven't stopped playing with the software since! It has a built-in iSight camera (very high quality webcam) and a great application colled PhotoBooth which lets you take pics and video and if you want, apply all sorts of affects. Needless to say... this is just too much fun to be believed. This is such a GREAT computer; highly recommended.

Anyway here are some pics:
