It may be goofy, it may be pointless, but the Photo Booth program is a bigger time drain than Solitaire, the Web, and Dancing with the Stars put together.
It’s a match made in heaven for any Mac with a camera above the screen. (Photo Booth doesn’t even open if your Mac doesn’t have some kind of camera.)
Open this program and then peer into the camera. Photo Booth acts like a digital mirror, showing whatever the camera sees—that is, you.
