World's First Tidal Powered Moon Clock
The five storey high structure is made up of three concentric translucent recycled glass rings that illuminate to provide information about the moon. With light generated from the tides, the rings show the Moon’s movement, current phase as well as the ebb and flow of the tides.
Created as both a waterside landmark and public sculpture, the Aluna Project hopes to create Aluna Moon Clocks in both London and Melbourne. [via]
