Seizure

With all these holidays, it seems that I missed another great exhibition: “Seizure” by Roger Hiorns (open until 3 January 2010). According to Guardian,

Hiorns filled a bedsit with 75,000 litres of copper sulphate solution, which hardened over several weeks into crystals. The installation secured him a nomination for the Turner Prize.

What you see on the walls (floor, ceiling etc.) is copper sulfate pentahydrate (CuSO₄·5H₂O). A stylish way to refurbish an apartment.
