Flickering Leaves

A large D shaped silver sculpture sitting on a pole with thousands of small metal round discs attached. Behind is a curved white building with many windows and a blue sky.
A close up of hundres of circular metal silver discs.

Changes in wind direction creates patterns in nature.

How it works

Spin the wheel to orient the flicker discs according to changes in wind direction.

Things to try or ask around the exhibit

  • Does the movement of the discs remind you of something in nature?
  • Which way should the discs face to maximise movement?

Background

This sculpture by Ned Kahn represents the movement of wind across fields of grass, or ponds of water. The manner in which the silver discs shimmer can be used to detect the direction of prevailing winds.

Finding the science in your world

Many Indigenous cultures rely on observations of natural phenomena such as wind patterns to forecast weather. Some cultures also build structures such as wind socks to gauge wind direction, which is important for airlines, agriculture and sporting events.
