Some smart guy figured out how to do this wild floor with just two different tiles.
It's almost an optical illusion as I try to figure out the pattern it keeps changing.
I left the lines I drew on the picture grasping how it worked as they might help you also.
He says it looks especially good on a round room but I wonder if alcohol would make it more fun.
I think the tile puter-downer would have to be extra careful not to screw up the design.
