Piet (programming language)

Piet program that prints 'Piet'

A "Hello World" program in Piet

Piet is an esoteric programming language designed by David Morgan-Mar, whose programs are bitmaps that look like abstract art. The compilation is guided by a "pointer" that moves around the image, from one continuous coloured region to the next. Variables are stored in memory as integers in a single stack. Most specified functions deal with operations on that stack, others with the rules by which the compilation pointer moves and with input/output. Piet was named after the Dutch painter Piet Mondriaan.
