I wish i had spent more time setting up my camera for this, this turned out to be the only good one from 8 pics i took.
It was taken at the Fact Cinema in Liverpool. They are know for their alternative exhbitions and this one is no exception. It is a zorb filled with helium, then attached with crayons. The ball can then be pushed around by the public creating the marks on the wall.
I would have waited to go back next week but no doubt there would be people in the way or something.
