Hundreds of colourful LEDs, duplicated thousands of times in a room, mirrored on the floor, walls and ceiling at the Tate Modern in London, make up the “Infinity Mirrored Room – Filled with the Brilliance of Life” exhibition. Two Infinity Mirror Rooms, Yayoi Kusama’s immersive installations, offer a glimpse into the artist’s universe. A number of photographs help to explain the phenomenon of mirrored rooms.
