In 1989 Castelli settled down in Paris and married two years later Alexandra, which he painted over and over again. He experimented with a home-made camera obscura and developed his Revolving Paintings. They can be turned 360° and have no defined upper edge. Depending on how they are hung, the viewer sees other faces, bodies, or city views. The motives "overlap and penetrate each other, giving supposedly abstract structures that turn out to be representational when the corresponding motive stays right," writes Peter K. Wehrli.[12]
