What is Photobooth?
1.
Possibly one of the most pointless, but fun, apps for a computer. EVER. It uses the built-in camera on an iMac or MacBook to take all sorts of goofy pictures. Not only can you take pictures, you can also do all sorts of goofy distortion effects, and color filters, such as thermal, X-Ray, and comic book.
PhotoBooth sucks up too much of my spare time.
