Sky wall

This was a show in Victoria Square, Birmingham. The theme was global warming and a related UN treaty (can't remember which).

It's difficult to describe... started with an office scene and a number of people working. The floor was slowly lifted to a vertical position, with the contents of the 'room' falling off and performers struggling to stay on.

The rest of the show involved acrobatics of the performers reacting to the scenes and images projected onto the wall (they were able to move horizontally and vertically - there were other performers dressed entirely in black on the sides of the wall who acted as counterweights).

The whole thing was quite incredible. And the blip shows a performer bouncing on a moving graph.
