With a few adjustments the tiles can morph vertically as well as horizontally. I might prefer the just-horizontal version, but I’m not sure.
In some ways I prefer the black and white to the color. When it’s just outlines your mind can interpret shapes any number of ways. When a fill color is added they get restricted a little. With additional colors they get more locked into regions.
This is such a good project to work on while I have insomnia. Or maybe it’s causing the insomnia.
