Hello World in Piet

Piet is a stack-based esoteric programming language in which programs look like abstract paintings. It uses 20 colors, of which 18 are related cyclically through a lightness cycle and a hue cycle. A single stack is used for data storage, together with some unusual operations.

Piet was invented by David Morgan-Mar and is named after geometric abstract art pioneer Piet Mondrian.
