Like a virgin, 2004
A staircase leads to an observatory built in front of a series of windows facing the roof. A diffuser intermittently releases into the room a blend of human pheromones. This volatile, odorless and low concentrated substance modifies the social and aesthetic perception of the room, depending on the sex and on the individual. While in the room, the public can look out of the window through a microperforated film. On the roof, birds are attracted by estrogen-treated maize. These sterilizing seeds are used in many cities to control the pigeon population. « Like a virgin », Madonna.
