After Prof. Levin’s lecture, I became interested in the concept of Truchet and Wang tiles. I made my own set of 16 tiles and an algorithm that allows me to join the tiles together according to a set of constraints. Of those 16 tiles, 1 is an unconnected shape, 4 connect to just 1 side, 4 connect to 2 adjacent sides, 2 connect to 2 opposite sides, 4 connect to 3 sides, and 1 connects to all 4 sides. That may be kind of confusing so I added in a little sketch I did while designing the tiles. 
Here is the p5.js sketch if you want to take a look: https://editor.p5js.org/adoro/sketches/JTZsRsIFz
The tiles are drawn in the tiles.js file and the constraints and drawing function are in the arrangeTiles.js file. I’ll add in scans of the riso prints I did soon 🙏.
