Ben’s stuff is solid. Below are a couple of examples. I believe these images were for Nickelodeon. I particularly like this first image because it is a character as a container. Cool. Beware - the site is a bit of a mess. It will keep resizing your windows. Nonetheless, the images are very worth exploring. And for once, the images are quite large, so you can really get a good look at them.

This site is for Animators. It is a Flash site (xml). It has various little "flip" animations. And some samples of lectures and what not. I don’t know anything about the quality of the school, but if the site is a reflection, then I have high hopes.
