Education
Drop bodies onto a canvas, drag to set their velocity, and watch gravity do the rest — including genuinely stable configurations like the famous figure-eight three-body orbit. A leapfrog integrator (not the naive method that makes orbits spiral out over time) keeps energy and angular momentum honest, with live conservation readouts proving it. Try the solar-system-lite preset or build a random cluster and watch it settle into orbits on its own.
