I'm going to play with ways to color a Snail's Trail block and see what happens.
What if I make the other two spirals black and then simply repeat the block?
What if I make the background a very light taupe?
What if I arrange eight blocks around a center square to make a new larger block and then repeat the larger block?
What if I candy-stripe the light grey background as well?
What if I use four reflected blocks to make a larger block?
What if I combine four of the larger blocks rotated?
What if I cap the grey background spirals with white corners?
What if I join two blocks rotated and add their reflection?
To be continued.....
