Thanks! The lowest I could get it without turning adjacent pixels the same color or simplifying the animation was about 42 and it just didn't seem worth the work to lose some of the smoothness of the piece. I stared at it for a while and finally said "50 will do."
really really cool! really stylish. I wonder if you could consolidate the color count at all? 50 just seems like quite a few!
you're the artist!! no matter what it looks amazing! thanks for sharing, can't wait to see what you do next.
