Well actually Innen Stadt Aussen, which losely translated means inside instead of outside, but with the twist that Stadt in German is also the word for city.
I was actually looking for a video that was screened at the exhibition of a truck, and other cities with a huge polished mirror attached to it. the result were some incredibly surreal images where the truck was moving in one direction, and everything in the mirror was moving in another. It was very disorienting.
What I did find was a video of the whole exhibition (without the truck sadly). Check it out though, my other favourite was the hose pipe attached to the ceiling, and a room which has been filled with smoke and multi-coloured LED lights.
