The first step in creating this effect was to get a hold of a 3D point cloud. I chose to do this by using photogramatry to capture a sculpture designed by a friend of mine. With a point cloud in hand I worked with Processing to find an interesting system to remap the cartesian coordinates as polar coordinates. Although it's simple enough to do a "correct" transformation form one coordinate system to the other I was looking for something that would lead to more abstract results. The final product was the moving image seen here.

This code-generated graphic was an exploration of color.
