Urban Archaeology's wicked Linx and Dome tiles are a radical departure from those squares in your bathroom, in more ways than one. Never mind their bulbous three-dimensionality; the interlocking tiles are made from 50% recycled marble, though they reportedly have a resin-like feel to them. Also, due to their chemical makeup, these tiles can't cut it in a wet environment--they're meant to be decorative and "dry zone" use only.
