Piet is a programming language in which programs look like
abstract paintings. You can view some sample programs, or if you just like Mondrian, why not make your own with the Mondrian Machine? Or maybe you don't like Mondrian but you do like programming, in which case you can check out other strange languages, such as Petrovich, where you can punish or reward your PC. Finally, if you don't like programming OR Mondrian, have a look at a silly gif of a kitten.
