An atlas of periodic solutions to the three-body problem.
The three-body problem has no general solution, but it has thousands of periodic orbits: three masses falling around each other and arriving, after one period, at precisely their starting positions and velocities.
The atlas
Every one of the 3,915 orbits has a place on the map. Orbits that look alike sit next to each other; the families form islands, and each family has its own page. Far out the map is a constellation, close up each orbit runs live, and any orbit opens on its own page, where it plays one period at a time, can be nudged off its track, rated and ranked in battles.
