FIELD GUIDE
The story
Horizon is a 1.5-metre acrylic sphere filled with water, and what it does is turn the Indian Ocean upside down.
A water-filled sphere acts as a lens. Stand in the right place on Geraldton's Beresford Foreshore and the sea, the sky and the horizon line appear inside the ball, inverted – the ocean above, the sky below. That single optical trick is the entire work, and it is the reason the sculpture has become one of the most photographed objects on the Western Australian coast. It is by the artist Lucy Humphrey.
