Olafur Eliasson - The Weather Project (2003)
“Representations of the sun and sky dominate the expanse of Turbine Hall. A fine mist permeates the space, as if creeping in from the environment outside. Throughout the day, the mist accumulates into faint, cloud-like formations, before dissipating across the space.
At the far end of the hall is a giant semi-circular form made of hundreds of mono-frequency lamps.
Generally used in street lighting, mono-frequency lamps emit light at such a narrow frequency that colors other than yellow and black are invisible, thus transforming the visual field around the sun into a vast duotone landscape.”
