A studio for growing geometry
Click or drag across the grid to grow a pattern. Each click is an origin. The selected shape walks outward for the number of steps you choose, cycling through the palette.
Seventeen shapes and fourteen palettes are available. Cell sizes range from 10 to 30 pixels. Switch between Colors and Numbers to inspect the underlying color indices.
Saved sequences replay your click origins. Saved patterns and their version history stay in this browser — they are not uploaded or shared across devices.
