GeYOPP: Generate your packing

GeYOPP lets you generate a dense random packing in a fun and interactive way.

GeYOPP (Generate Your Own Particle Packing) lets you explore the connections between shape, randomness, and packing in a fun and interactive way. Use your imagination to draw a shape, then perform an experiment on your smartphone to generate a dense random packing.

Can you find the shape that packs the densest?

With GeYOPP you can:

- Draw an arbitrary two-dimensional convex shape or select a shape from a catalogue of exotic shapes

- Choose the number of shapes you want to pack

- Apply gravity by shaking your phone to pack your shapes into a dense random packing

- Compare your packing density with other users on the GeYOPP leaderboard

- Create a unique and personal image of your packing to share with friends
