We walked through the Tate Modern where the Turbine Hall has a great installation titled ‘How It Is’ by Polish artist Miroslaw Balka. Its simply a huge, intensely dark room, open at one end allowing you to walk towards the overwhelming, infinite blackness. It is very cleverly designed to trick you into believing the darkness goes on further than it actually does, the volume seen from the exterior is different from the interior. I won’t give it all away here but go and see it while you can, it is like the exact opposite of Anthony Gormley’s Blind Light (where you lost yourself in thick whiteness). Slightly frightening, extremely exciting.
