Pixeloo is a blog I found through Blogspot's "Blogs of Note." The Blogger Team looks for "Interesting and noteworthy Blogger-powered blogs" though some of the blogs they feature are not hosted by Blogger. Anyway, I went to the Pixeloo blog and was happily entertained by watching Jax (I derived this name from the email he posted because I like it better than Pixeloo) make a cartoon Jessica Rabbit into realistic textured Jessica Rabbit. It was too cool.
He's also done a Mario, Homer Simpson, and a Stewie. They are a little creepier in my opinion, but still cool.
Jax links to another site with pictures of more 'untooning,' but not all of their stuff is as good as Jax's. Have fun!
