This is a small graphic script attached to a graph box; draws a bunch of circles in just the right places. The black outlines and transparent red fills conspire to make the edge and moire effects. Sin and Cos are swapped to get a traditional orientation.

Running the script is a lot more fun! Removed the picture's link to a blog entry.
I <3 this.
