Still playing with the optimal Truchet pattern generation... So, the final technique is this:
- fill two layers, one with each pattern (I create the patterns in a side image and copy to clipboard)
- add layer mask to top one
- fill with noise (plasma or HSV noise, each has its advantages)
- Filter/blur/pixellize and give the size of the pattern
- use threshold tool to obtain equal number of black/white squares, or a pattern mix you like (this is the fun part, watching the pattern evolve while you drag the threshold handle).
But then there is a variant:
- add layer mask
- create text on layer mask
- pixellize & treshold as above.
Instant steganography. Can you spot the letter?

Hint: it's more visible if you look at your screen from a distance, and are a bit on the side (ideally 45 degrees).
Did I say subliminal messages in screen savers? No I didn't! Just plain squiggly lines, boss... and look, do you see anything else?
