How this works

Every grain you drop is duplicated around the center at N evenly spaced angles (360°/N), the same reflective repetition Tibetan Buddhist monks build up by hand, grain by grain, over days, before ritually sweeping the finished pattern away.

Each pointer position is converted to a polar angle and radius from the canvas center.
The angle is copied N times, evenly spaced around the full circle, so one gesture becomes an N-fold symmetric mark.
Grains are drawn as small soft-edged dots that accumulate on an off-screen buffer, so thousands can be placed without redrawing history each frame.
