Stage: 3, 4 and 5 Challenge Level: 
One of the installations was called "Turning the Place Over", created by the artist Richard Wilson.
It runs in daylight hours, triggered by a light sensor and involves revolving a huge (8 metre diameter) circular disk which was cut from the front of an old office block. An axle and motor was attached to the disk to, literally, turn it around.
Can you work out how the axle must have been placed and attached to achieve the effect shown in the video and accompanying still photographs?
