"Richard Wilson’s 20:50 is truly a contemporary masterpiece. The work is the only permanent installation at the Saatchi Gallery and has been continuously shown in each of the gallery’s venues since 1991. Currently on display in Gallery 13 – a room custom built for the piece – 20:50 transforms the gallery into a site of epic illusion.
Viewed from the entrance platform 20:50 appears as a holographic field: simultaneously a polished floor, infinite clear pool, an expansive and indefinable virtual space that clinically absorbs and mirrors the gallery architecture. The room is in fact entirely flooded in oil.
20:50 takes its name from the type of recycled engine oil used. It is thick, pitch black, and absolutely indelible" Saatchi Gallery
