Playing with Blocks
It's hard to see any pattern at all. This reads as texture. Only by looking really hard can I see a series of X's and O's.
What if I color the X's green and leave the O's brown?
I can see the checkerboard pattern now.
What if I tone down the contrast by replacing the white with light colors?
This has the autumnal feel of fallen leaves to me.
