Sebastien Truchet played with square tiles, diagonally divided into black and white, in 1704. He could make some startling patterns with this simple alphabet. Cyril Stanley Smith played with two tiles, each with two quarter circles. This produced an homogenous set of patterns.

When I got to playing with Truchet Knots, it was with Smith's two quarter circle tiles, and another two tiles with straight lines. I'm not certain who to credit with that advance. But it was on Reddit's r/generative that I found someone had followed the lines, and coloured the "knots". This inspired me to start exploring.

Started experimenting with widths

First explorations of walking the path and assigning colours (buggy).

Soon came to the realization that capped weren't as interesting for colour.

Finally found that sequentially assigning the colours gives a more satisfying, organic feel. But we're not done yet.

It was about this time I found that adjusting the ratio of tiles could have a dramatic impact on the design.

Started exploring the effect of adding black to the colour palette, and increasing the tile density.

Following an exchange on Reddit, I began experimenting with straight-only designs.

I became intrigued with working messages into the design, so I developed an alphabet.
