Piet Program Gallery

How Piet Works

Piet is an esoteric programming language where programs look like abstract art. The language uses 20 colors:

The program pointer moves through colored regions. Operations are determined by the hue change and lightness change between regions:

• Hue cycles: Red → Yellow → Green → Cyan → Blue → Magenta → Red
• Lightness cycles: Light → Normal → Dark → Light
• White blocks are free movement zones
• Black blocks are walls
