I realize that I skipped a step. If, instead of pixels being only off or on, you use a wave function for brightness (value) where the period of the wave is each pixels' radius, you get a much smoother pattern. The #Pixelblaze code is short and relatively simple: https://gist.github.com/jasoncoon/dbda5f390872cec21ec2ba875ff5b14f

Something I find really neat about the pattern in the previous post: if you watch any individual pixel, aside from it changing colors it just smoothly blinks off and on at the same rate the entire time. The further the pixel is from the center the faster it blinks. It's a similar "incremental drift" mechanic as a pendulum wave:

@jasoncoon Just wanted to throw it out there, I absolutely love my Fibonacci. It's quite the conversation piece, and I can just sit and watch and get lost in it.
