40m-wide lunar clock heading for London by 2012

Plans are underway to build a 40m-wide lunar clock by the River Thames, in time for the London 2012 Olympic Games. The proposed site is East India Dock – around six miles away from the capitol’s current king of time-keeping Big Ben. The clock, named Aluna, will be powered by the river:

“There are three giant concentric rings made from recycled glass – light shines through from the glass in time with the Moon’s cycles so the largest ring shows the lunar phase. The second ring is like the big hand of the clock [and] the third ring – the smallest – is the small hand that tracks the tide as it goes from high tide to low.”

Add it to your ’should visit’ list, along with the Olympic Games itself. (Via: BBC)
