There is a tile floor in my office that is lots of little squares. The little squares are blue and yellow. Each color is clustered together to make larger squares that are each 8x8 tiles big.
When I'm in that room, my brain always tries to make new blocks of patterns. This one will be 4x4 of both colors. That one will be a long row. Another will have a four quadrants. Another will be 75% of one color and 25% of the other. My brain can't help but see new shapes.
I'm not sure if this my brain trying to amuse itself during a quiet period or some weird byproduct of spatial mathematics. I'm not bothered by it; I just think it's interesting that this is how my brain works. I notice it with wall paper and carpet designs too. Something about patterns makes my brain go, "Okay, but what if....?"
Do you ever try to make patterns out of other patterns?
