Just found out about this website, which I think I'll be going to regularly!
My favorite part of the site is 123D Catch. It's really neat; you take 20-40 photos of an object or person from multiple angles and upload them, and the site will create a 3D render of it that you can rotate and look at from all angles. It even has simple tools you can use to clean up the 3D render it creates. Looks really awesome, and it's great for figure drawing practice. There's an iPad/iPhone app too.
