WebOS!

A command-line based 3-body problem visualiser, simulator, and renderer, with live terminal-visual modes, png-render output, or infinite brute-force configuration finder functions. Highly customisable; every aspect from masses, gravity, positions and velocities, simulation time steps, etc. can be customised with extensive CLI flags. Great as a screen saver, or for accurate (rk4) renders of three bodies. Enjoy :D
