I stumbled across this program last night called Motion Picture and found it super interesting (for all the animators out there!) http://www.motionportrait.com/e/
Ok so basically Motion Picture is a simple animation program. You take a photo of a person and the program creates a 3D model of it and that model can then be animated.
This animation can be used on the web, animations, and games. You can also change the model in the animation, with different, hairstyles, backgrounds, outfits, eye colour etc.
It looks like a nifty program, but does have some limitations.
