My cousin SMWS was frustrated that http://sketchfu.com/ was going unmaintained and that Muzy was slow and required Flash, so I thought I’d write a quick HTML5 clone. I wrote most of the code, but he did a lot of the interaction design and some of the internal software architecture.

At this point, it’s possible to use it to create worthwhile drawings. Try http://kragen.github.com/aikidraw/aikidraw.html.
