Here's a video about the exhibition:
I really wish that I had taken my video camera to film this. I only took my camera and the movie setting on it isn't great but at least I managed to video some of the balls disappearing into clouds and the giant bubbles which were my favourite part of this film. I've never seen a film done this way before. Vertical images seemed to fall from the giant screen like rain drops disappearing into the ground. I loved the way this was done, it was quite exhilarating to see something so different.
