A sneaky peak at what will be on show on Friday at the exhibition. Photos by the artist replete.
Been down there today painting some boards white for the live art. Moving sand bags around and putting them on to the frames for the boards so they can't fall. The building it's self is really interesting. When it was built it was said to of housed the largest room in the world. The architecture is amazing.
