GeYOPP: Generate your own particle packing app for iPhone and iPad

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 iPhone 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
