Adventure Time is an awesome animated short by Pendleton Ward, who also has a site with some cartoons, animation, comics, and a blog.

The Comic Book Bondage Cover of the Day - Massive archive of... well, it's pretty self-explanatory.
What happens when crude Flash animation meets an absurd sense of humour? The surreal serial Weird Emma, that's what. If Emma's not up your alley, maybe you'd prefer the static cartoons of Wulff Morgenthaler.
