We recently told you about land artist Chris Drury's amazing adventures in the Antarctic (see Ice sculptor). Here's another of his projects – this one a Wave Chamber he built in 1996 in Kielder Water and Forest Park, Northumberland, England.
This striking beehive-shaped hut is 4m high and was created from 80 tons of stone. As the sketch above shows, it also works as a camera obscura (basically, a primitive camera that uses projection to create images) – it has a lens and mirror built into its top, which is angled to face the reservoir. This produces a projection of rippling water onto the floor of the hut, which also echoes the sound of the waves outside.
