Aluna is an amazing proposal for the world’s first tidal powered Moon Clock.

Larger than Stonehenge, Aluna’s forty metre wide, five storey high structure is made up of three concentric translucent glass rings. By looking at how each ring is illuminated, you can follow the Moon’s movements, its current phase and the ebb and flow of the tides. This animation of light is called Alunatime.

Using the latest design and technologies, Alunatime will be powered directly by the tides using turbines. A waterside landmark and a public sculpture, Aluna unites art, science and spirituality and is an ever-changing reminder of the natural cycles that have shaped our past and will determine our future. Very nice, let's just hope they find the money to get it built.
