Posted: 2011-04-07T20:44:49-07:00
The code at the bottom of this post was used to create this image:
I wanted to have another option besides swirl: Reflect. Reflect would take each frame, flop it and append it to the original so the colors would radiate from the center instead of go in one direction. I used append to create the gradients but couldn't get it to work on each frame of the animation. Here is what I expected to work:
