The kids of the future will have it so nice. If they want to learn anatomy they won't have to bother with books or live drawing courses. Just open up the browser and take an in depth look at the human anatomy in 3D. Choose any pose, angle, lighting, expression, gender, whatnot. Pretty fucking awesome.

If you got the latest Google Chrome beta(which supports WebGL) you can enjoy these harbingers:

I'm wetting my pants imagining how something like that could improve Doodler ... I might actually give it a try

latest firefox 4 beta also works, I believe.

Awesome. Could've used it 6 years ago but it's just as fun today :D

Life drawing classes will always be good! :D
