About 8 years ago I got interested in games like Tsuro & Tongiaki. In particular, I was interested in the combinatorics of the tiles. How many unique tiles are there for each different shape of tile? The answer is related to sequence A132100 of the Online Encyclopedia of Integer Sequences. While I was playing around with that, I spent a lot of time drawing different tiles using a simple Processing sketch which I wrote. I posted that here, but it has gotten kind of crufty and hard to keep running because of Java-rot.
So I decided to whip up a new version. This one uses React & SVG and makes a nice, simple standalone page with no complicated plugins. You can find the source here, or if you just want to play with it, you can run it here.
