Last time I played with harmony sketch, I found a cool bug/feature. I wanted to know if you knew about it…
If you open it up and use the grid mode to draw a bunch of dots on the screen, then switch to a different mode (like long fur) and hit clear it will immediately render all of the grid dots connected with fur. You can then cancel and save the image. I know it works in safari… not sure about other browsers. Is that an intentional behavior?
Some time ago I also started with a 3d engine (path tracer). If anyone like to have some code: http://thuijzer.nl/jsrender/ (I never took time to optimize/bugfix the code).
Fantastic work. I wonder how long before this sort of thing can be used to do 3D development on the mobile web for devices with full browsers (iPhone, Palm Pre, Android, etc...)
Lots of other incredible demos on his portfolio page: http://mrdoob.com/blog
