Rik Andreae pointed me to Leandro Erlich’s “Swimming Pool” installation which can be found at the 21st Century Museum of Contemporary Art (in Kanazawa, Japan). I believe you remember previous Japanese girls with small heads illusion. Also we had a performer that done pretty similar installation. His name is Philippe Ramette. I think that the below photo is done with realistic statues instead performers, but am not sure. Anyone has more info?
