Everybody should remove their shoes, because they were told that they should walk barefoot, with no shoes, that you feel the surface is not even. And this is true story tell when one of the security guards of the Museum of Contemporary Art. It was one day in the wintertime, was nice and warm inside. It's very lovely, very soft floor, very silences. And the security guard was closing the museum, and is walking around to see that everything is okay, and he find in the stairway—was also wrapped—on the floor, young couple making love. That is one of the loveliest compliments of our project. The thing was so intimate, so suitable, that they used the floor to make love.
