The subject of the weather has long shaped the content of everyday conversation. The eighteenth-century writer Samuel Johnson famously remarked ‘It is commonly observed, that when two Englishmen meet, their first talk is of the weather; they are in haste to tell each other, what each must already know, that it is hot or cold, bright or cloudy, windy or calm.

Representations of the sun and sky dominate the expanse of the 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. A glance overhead, to see where the mist might escape, reveals that the ceiling of the Turbine Hall has disappeared, replaced by a reflection of the space below. At the far end of the hall is a giant semi-circular form made up of hundreds of mono-frequency lamps. The arc repeated in the mirror overhead produces a sphere of dazzling radiance linking the real space with the reflection.

Taken last sat in London when I went to meet *nuozek and various other people, this was exhibited in the Tate modern, the exhibition has been taken down now. This panarama was done by hand too, little bit blurry because of the smoke machines..
