Just got my first Mac on Saturday, and boy is it a beautiful machine (24"). However, i did notice that while playing around w/ photo booth and the iSight camera that sometimes the camera seems to go "off-color" and get brightly colored random small lines in the background (the best way i could describe it is that i seem to look blue in the camera and it looks like someone threw brightly colored confetti in the background) and it's not one of the preset effects... has anyone else experienced this?
