The funny thing about regular practice with the Zentangle® method, is people usually start to see tangle patterns constantly. I can no longer look at a building, a flower, or fabric without seeing the patterns first then the whole of the item. It's an interesting new way of looking at the world.
I also find myself drawn to black and white patterned items. I have many shirts that look tangled, and I even splurged on some Sally Hansen nail strips that look like mini tangles. I had to pop these on for my next class. :-)
