This is amazing. I was just surfing around randomly this evening and hit upon this ingenious 3 dimensional pattern, which in reality is a simple mat/potholder. The pattern reminds me of the magnificent marble floors

in the grand Italian churches, which in reality are flat but convey the illusion that each block is a stairstep beneath your feet.
