Encounter with Richard Wilson's '20:50' at the Saatchi Gallery

When I first walked into the room and looked down over the small balcony, it appeared I was just staring into a space that had been darkened at the bottom. I then looked right over the balcony and saw my reflection, and then realised from the oil smell that this room was actually filled waist high with oil. This piece changes the perception of space, as it makes the room seem very large. The metal walkway almost seems like it is hovering within the space. I was mesmerised by this whole concept.
