That looks like SketchFighter 4000 maps lol, a fun little game IMO

Very nice!

I still love what you do. What is the size of each piece of map?

Thanks!

I don’t have them at hand right now, but they must be barely over an inch on the short side.

…with uniformly-tessellating paper sizes, you’ll have cave geomorphs…

Oh, it’s a game! At first I thought it was a pen, then a map drawing app, then a geomorph set.
