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.

Developer Response ,

Yeah, I'd neglected OpEvol for a while. I didn't know it was bonked until someone emailed me to let me know. Version 1.1.3 should be better.

Customizable for optimum relaxation and enjoyment

My favorite thing about this app is the ability to control the colors, shapes, and especially the speed of changing shapes. I find that I most often turn down the speed from the default speed for maximum relaxation.

Guy must not care anymore

iOS 15.4, stuck on one design, no controls. Boo.
