Diffusion Curves: The next advancement in vector illustrations

I've done a couple of gradient mesh works using Illustrator.  The G-mesh tool in Illustrator works to create organic looking work, but a drawing can become extremely tedious.

Some guys have created what appears to be the perfect solution with Diffusion Curves.  It's difficult to explain how it works, so watch the video:

The tool itself includes a few other clever ideas that I wouldn't mind seeing in Inkscape, such as the "active contour" feature that attracts curves to the contour of underlying image.

I haven't yet tried the tool, but you can download it at the Diffusion Curves publication page.
