In the process of going through my old saved tweets as I transition away from Twitter, I saw this tweet from Dave Richeson who is now posts on Bluesky as @divbyzero.bsky.social. About one year after this, I made a LEGO Truchet tiling for Dave, not realizing that I had probably been unconsciously inspired by his!

Recently I saw a post on Mathstodon from @diamabolo, which goes a step further: a LEGO Truchet Tile Machine!

When I went to make my own LEGO Truchet, I used LEGO Studio to make some digital mockups, find the part numbers, and by the pieces in bulk via Bricklink.

I ordered 172.46€ worth of parts from Germany—enough to make eight different tilings, three of which are shown below.
Building for Dave Richeson
One tiling was based on a post by Dave Richeson’s bot @randomtiling.bsky.social, which I mailed to him. Here’s a picture of the work-in-progress.
The design was based on an actual post from Random Tiling Bot (@randomtiling), which I can’t find now. This one is close enough:
LEGO part numbers
The 10 x 10 Truchet tiling I made for Dave is made from two different LEGO parts together with a 32 x 32 gray baseplate.
- Part 25269 — Tile, Round 1 x 1 Quarter
- Part 3396 — Tile, Modified 2 x 2 with 2 1 x 1 Curved Cutouts (Double Arrow)
