ALT A photograph of a green field with trees beyond and and a grey cloudy sky. At the centre of this pastoral idyll is a rectangle of randomly placed dots of light, almost as if a second image has overlaid the first. The photograph was taken near Nairobi, Kenya and the dots represent the density of air particulates present at the time. Photograph by Robin Price

ALT A photo taken inside the gallery. The walls are grey, with text in orange that reads, 'This is not a table'. There is a table, but it's lit up with multiple LED lights from it's interior, so it's definitely not a regular table. The lights have been programmed to show an expansive rainbow of colour. There is a net across the centre, a ping pong ball and table tennis bats on the table ready for visitors to play.
