Yet another map generator! This one for Terraria. I actually just looked while writing this, and the readme says it doesn't support colours, but there are a bunch of uncommitted changes and some brightly-coloured sample images from about a year and a half ago. Guess I'll commit those... better late than never!
This is the first GitHub repo for which I ever received a pull request, and it came out of the blue. That was nice. Social coding!
Future plans: An obvious upgrade for this app would be to get it working with Starbound. Possible? No idea... I'll have to find out!
