I've been very taken by the idea of using my 18 degree fan ruler to make something spiky and saw blade inspired. It should be possible to cut wedges out of joined strips, with fairly little waste, if both color combinations are made at once.
Using these effectively is hard, though. If I make the half way point of an edge connect to the next, there's lots of layouts to use, but I don't really like the ratio of dark to light within a square.
Here's a possible lazy fix, but it doesn't really please me.
Scale seems like it might be important here, so I should probably make some actual size samples and tape them to the wall.
