A pebble fits in your pocket. Its story can be bigger than humanity's.
Pocket Rocks turns that feeling into a small collecting room. Find an individual digital specimen from ten geology-inspired families. Turn it over, keep a favorite, and build a cabinet of shapes, colors and mineral-like patterns. A stable family and seed let you share the same rock with someone else.
The cabinet stays in your browser. Save an SVG artwork, export a JSON backup, or import a cabinet on another device. Collection is free. These are procedural digital art objects inspired by geology. Saved entries can be shared and reproduced by seed.
