Inspired by Op Art of the 1960s, OpEvol takes the geometric play of colors and contrasts and animates them into a moving field of ever-changing psychedelic eye candy. It's for staring at. It's for sending to Air Display. It's for playing with, and then staring at it some more.
These look super good on my retina Mini.
