While having a piss, I thought it would be kinda funny if planets went 'beep' when they passed each other. Bigger planets going 'booop' and little ones going 'bip'. So I made a sketch, mouse buttons move around and that. It doesn't work very well and the sound goes crackly. Planets are generated randomly so sometimes it sounds more awful than others.

Then I thought, looking at the noise that's produced as a repeating pattern then that pattern is encoded in very little information ((radius, orbit radius, angular velocity) * num planets). I might think about that later if there's anything worth thinking about.
