For Perry Hall, the videos Circular Ruin, Faithful Animal, Paintshifter Number 1 and Tidal Empire (Animist), created specifically for the ArchiLab 2013 exhibition (Naturalising Architecture), are paintings. Using a super high-definition digital camera, the artist films live the behaviour of the coloured liquid material which he prepares beforehand through a mix of substances (oil and water) and the use of stimuli. He shakes, provokes sound vibrations or introduces magnetic fluids (ferrofluids) in order to set the matter in motion and conceive painting as a dynamic process that unfolds in time. The pictorial events that occur, both man-made and random, are visually very close to natural phenomena: lava flows, torrential mudslides, whirlpools and other tidal movements. They also reveal painting as an intelligent matter capable of self-organising in a semi-autonomous manner and of growing.
