Isn't that funny, floors hadn't occurred to me, but yes, there would be some great patterns. We've laid tile in various places of the house. One of my favorites is the bathroom counter. I did it in tumbled marble tiles, and made them look like a cobblestone street. Some of the architecture in the older cities is gorgeous. I could definitely see inspiration there. And in the stained glass and such in some of the chapels.... oooh.
