Around 2001, Wim Delvoye. asked some of his friends to paint parts of their bodies with small amounts of barium and then have sex in actual medical clinics. At exhibitions, the X-rays are presented as giant stained-glass church windows. At a distance you admire the abstract forms, but it is only when you come closer and study it in detail that you see what it is composed of.
