"Tower of Light" by Andrew Drummond

Presented to the city in 2005, sponsored by Meridian Energy, and assisted by the Wellington City Council, Tower of Light is the second major work by Andrew Drummond to be installed in Wellington. He is known for sculptures that involve technology and explore the relationship humans have with technology.
Tower of Light is a machine that uses the wind speed and converts that into light using very simple technology. The rotor at the top of the tower spins in accordance to the wind speed. This rotational speed is read via a controller, which then switches on neon rings in accordance to the speed of the rotor, which is determined by the wind speed. The lighter the wind speed the fewer number of rings are lit and as the wind speed increases the more neon rings are lit. The artist has used rainbow colours as a measuring element and so the sequence goes from blue and violet at the bottom through the spectrum to red at the top. As a result, the viewer is able to read wind speed through colour, a method for them to re-sense their environment.
