From Chaotic Software:
Video Funhouse turns your Macintosh and video camera into a virtual funhouse! Using a palette of easy to use tools, you can twist, bulge, pinch and push your face into virtually any shape imaginable. Unlike other 'goo' applications, Video Funhouse lets you do all this with either live video from your camera or any static image of your choosing. Pull on your ears, make your eyes bulge out, pinch your nose - the fun is endless!
