Well, what a difference proper mapping makes. I mapped the proper Fibonacci order (radius from the center out) and the spirals, waves, etc, really stand out now.
I still like the smooth spinning effect given by using the physical, unmapped order (pseudo nearest neighbor, from outside in), so I’ve made variants of several patterns using both. Mark’s Pride2015 pattern also looks especially amazing now: https://youtu.be/4gHrsgkmIo4?list=PLUYGVM-2vDxJLjAv6qwl_FOBu8xzAoJL4
I also completed two different XY maps (much simpler than my previous 3D array attempt), here’s a video of some XY based patterns (wipes, noise, fades, waves, fire, etc), with some 1D strip patterns (rainbow, bpm, juggle, twinkles, etc) mixed in: https://youtu.be/k1uY6yGgAB8?list=PLUYGVM-2vDxJLjAv6qwl_FOBu8xzAoJL4
