I quite liked this layout and made some "pictures" like these.
Two weeks later.
I tried the old trick of putting all my scraps into a large bag (scraps are anything less than three inches square, anything else is fabric) and pulled out one piece randomly at a time. If it was low-value it got sewn to the previous piece, if it wasn't it got rejected. I made a few blocks, which somehow gradually got brighter and brighter.
