An idea to fix a broken tile area. Don't tear out the wall of tile, make light of it! Caulk the broken/missing tile to waterproof, then add an air fern (kitchen backsplash) or a fake plant (shower or tub area).
One of my favorite things. It tessellates but doesn't have a repeating pattern -- blows my mind. I want it as a bathroom floor or something. These look like cement tiles. I should get on figuring out how to make them.
