During winter term of 2007 I took an Image Flow and Synthesis class. I have yet to post any of the code to the projects we did there. They included things like Gaussian pyramids and painterly rendering. I made some cool stuff in that class.

A faulty result of one of my advecting the image color along a rotation of the greyscale image gradient vector caused the picture to look something like a watercolor version of the original. I decided to soup up my original project, rewriting it as a framebuffer/GPU shader applied per-pixel to the image. This is the result.

Consult the flowchart for further information.
