hexflake

Drag on the canvas above to draw on a hex grid. Drag on drawn hexes to erase. Change the draw color with the slider. The "grid" button toggles the background hex grid. Click the "change symmetry" button to toggle between 12-fold mirror and 6-fold rotational symmetries. The "random hexflake" button generates a random snowflake with the chosen symmetry.
