I really kinda like this one. Though - for whatever it's worth - it's easier to appreciate in a larger format. I have some of these set to screensaver on my flatscreen tv. I sat there staring at it for hours when I first put it up. Yeah yeah, I know: narcissistic much? But it is fascinating to me. 
The title feels clunky, but whatever...
