Are you a big fan of animation? If that's so, then you should check out Muvizu.
By using Muvizu, you have the ability to make animated movies. All you have to do is download Muvizu and you're set to becoming a Pixar wannabee.
Personally, I havent really tried it out. Not because I'm not into it, but more of I don't have the time to. *Bitter
