Tate recreates 1971 art sensation

Revival of infamous Bodyspacemotionthings exhibition allows Tate audience to crawl, clamber, balance and slide.

In 1971 The Guardian’s reporter noted: 'Some of the 1,500 visitors became so intoxicated by [the] opportunities that they went around 'jumping and screaming' to quote the exhibitions keeper, Mr Michael Compton. They went berserk on the giant see-saws, and they loosened the boards on other exhibits by trampling on them. ... 'It was just a case of exceptionally exuberant or energetic participation,' Mr Compton said tolerantly'

Tilted room

A tilted room is extremely disturbing. It is hard to walk, and even to stand up. This happens when the visual sense provides information which does not agree with sensations from gravity. This is disturbing for astronauts living in a zero-gravity environment, and often causes severe disorientation illusions and space sickness. It also happens to pilots executing roll manoeuvres. Their disorientation can be so severe that they lose control and crash. It also happens to old people and people suffering from vertigo.
