If you know of any cool software or websites let everyone know about them here.
I love this software.. it's free from google.. it's for making 3-d designs.

It's so addictive.. but I am a sculptor.. maybe that's why I like it so much. it's pretty easy to use.. and they have a lot of free tutorials, too. When you do really complex stuff it can get difficult.. but it's still a lot of fun.. check out what this guy did with it..
