'Seizure' by Roger Hiorns - London flat encrusted with copper sulphite crystals.

An excerpt of his statement at ArtForum:

Once we found the location, the production itself was conceptual: I wanted to introduce a material that was anathema to the building itself. Crystallization is always, for me, a kind of claiming—I say “claiming” because the process is so amplified here as to be a kind of obfuscation of the building. I’ve encouraged an alien aesthetic, one quite contrary to its vaguely modernist history (with its roots in Le Corbusier’s designs). The building has a certain sort of governing rationality; by introducing these crystals, I’ve introduced some irrationality. The process also allows me to remove myself from the equation; crystallization is an autogenesis, and its results are an auto-aesthetic. I get to become an objective viewer of my own processes, at least to the extent possible. It’s a psychological position to take, to try and obsolete myself within my own realm of activity.
