An artist from São Paulo, Regina Silveira has created a fun and visually intriguing installation called "Depth".
Repetitive digital drawings of the windows and pillars in a mall is applied to its floor, creating an optical illusion that onlookers are walking on air.
In another installation, the artist plays around with lights and perspective to create shadows showing art objects being projected from empty pedestals.
