Gravity Loom — Spin a disk of dust around masses you place

A disk of luminous dust, simulated on your graphics card, orbiting masses you create and move. Trails persist like afterimages — phosphenes of where the light has been.

Every grain feels every mass, pulled by the inverse square of the distance, and keeps its momentum.

The Institute reconstructs the Vael system’s debris from the Atlas of Near Stars with a loom like this one, running for months at a time.
