I saw a work of op art on the web and decided to recreate it in Twoville:
You can change the number of rows, but don't go crazy. Your browser will suffer.
The op art movement began in the 1960s. Instead of a sensuous color palette, you get contrast. Instead of representation, you get abstract geometric forms. It's the kind of art you make when your brush is code.
I would never hang this on my wall. Or maybe I would, but only with its 40 lines of code right next to it.
