Fun Booth is the Web cam software that lets you take laugh-out-loud funny, scary, or outright silly digital photos of yourself
Fun Booth uses advanced face-tracking algorithms to perform real-time tracking of your face using your webcam / isight on macs to apply funny and real life props on your face.
It includes Props Dock that let you access all your props and disguises. Built in control and settings allow you to modify camera output in real time and also allow you to adjust the prop more accurately to your face. It also allows you to export your taken photos in many ways including exporting to Flickr.
