Roger Hiorns, Seizure (2008).
It’s almost as if Roger Hiorns has turned Yayoi Kusama’s illusions into reality. He has long been experimenting with household cleaners, detergents, perfume, fire and now copper sulfate, creating organic, unpredictable works of art. For his latest piece, Hiorns covered the walls of an abandoned apartment with a copper sulfate solution, which, after a few weeks, transformed into bright blue copper sulphate crystals.
