When you think of a squat you might think of dirt and a lot of sitting down, squatting even. In fact many different people squat empty buildings in very diverse ways. In Bristol there are hundreds of abandoned buildings. A few of them have become some of the most exciting new centres of visual and performing arts in the city. Appearing and then vanishing again. In fact there is not much sitting down involved, especially when the aim is often to leave a building in better condition than it was found in.
