The Apple iSight is a great piece of technology-a high-quality webcam and digital camera complete with useful software. Mac OS X comes with Photo Booth and iChat, both programs that take advantage of the iSight. iMovie, part of the iLife suite, also utilizes iSight. Current Macs come with the iSight built right in to the monitor, so there's no need for separate setup.
