Yikes! I still hate the "duality" meaning of the masonic checkerboard floor! I will have to use brain bleach for that not to bother me.
I moved into a house with a kitchen floor like that and changed it immediately. I realize that a black and white floor is not the "sole property" of Fɾҽҽmαsσɳɾყ, but I'd just rather not go there. You can't unknow what you know.
