A procedural generator for science-fictional planets. Source
Since I made this generator two years ago, it's been used in multiple game projects and pen and paper sessions. There's been a repeated request for the ability to download the image of the planet. I didn't know how to do this, so it took until I was given some code from Efface Studios on GitHub to make this work.
And since I was digging around in the code anyway, I proceeded to make some more additions.
