The Infinity Mirror Rooms in the Yayoi Kusama: Infinity Mirrors exhibit at the Cleveland Museum of Art are amazing. You, and maybe 1 to 3 other people, enter a small room and stand in a small area in the center of the room. Mirrors and lights and sculptures and effects take place as you gaze at infinite copies. It's like a fun house mirror room on steroids. In 20 or 30 seconds the door will open and the next group will be invited in.
One of my favorites was the Infinity Mirror Room - Phalli's Field. In 1965, Kusama integrated mirrors into her art for the first time, using the reflective material to line the interior of Infinity Mirrored Room-Phalli's Field. Through the kaleidoscopic relationship between the mirrors and the materials inside the chamber, complex patterns emerged, appearing to extend infinitely in all directions. #infinitekusama
