Leandro Erlich piece from MOMA's PS1 in Queens, New York. I got to see this thing first hand while in NYC recently. A very creative exhibit, what appears to be a deep swimming pool is nothing but a few inches of shallow water laying on top of a thick piece of plexiglass. From above, if looking down into the pool, it appears that if there is anyone in the pool that they are walking in the water. From below, it appears that the people are being seen from underwater. So cool.My pics & video from the PS1 can be found here.
