The Aluna sculpture will light up to show the movements of the Moon and the sea. An animation of light will flow slowly around the rings, which individually represent: the lunar phase (the wax and wane of the Moon), the lunar day (the rise and set of the Moon), and the ebb and flow of the tide. The Aluna will not reflect the Moon’s light (an impossible mission in a modern city) instead it would use a matrix of LEDs powered by energy harnessed directly from the Moon's tides via on-site tidal turbines. 

Currently there are plans to build Aluna clocks in the UK and Australia at a cost of between 8-10 million dollars each (depending on the size and location). Building is scheduled to take about two years. The Aluna designers see the sculpture as a combination of artistic, scientific and educational project. People will be able to “interact” with the Aluna, walk around the sculpture, enjoy the large space in its centre, and sit on the lower part of the Lunar Phase ring.
