I did a search on Truchet and found, among other things, this page:

Huff's layered tiles in the 99.1 image made me wonder, if the system
would work in 3D as well.
It does, but as you can see in the attachment, it does get a little
confusing to look at. Using a reflecting texture doesn't help, I
suppose.

BTW, the Dragon curve is a fractal thingie. See
