Halo’s gleaming surface catches the sunlight. This remarkable sculpture stands tall here in Central Park. The Halo is more than just an artwork. It is a testament to innovative engineering and artistic vision.
The Halo sculpture was created by Jennifer Turpin and Michaelie Crawford of Turpin + Crawford Studio. They designed it as a collaboration with nature. The sculpture responds to the wind’s kinetic energy.
Halo was officially opened on August 14 2012. It has since been donated to the City of Sydney as part of its City Art Collection. The Halo is a wind-powered kinetic sculpture.
Look up. Notice the 13-meter high angled silver mast. See how it supports a 6-meter long silver arm. This arm holds a 12-meter diameter tapered yellow ring. The ring pivots gracefully. It turns and tilts in response to the wind. This creates a mesmerizing dance.
The Halo’s design is minimalist. Its wind-driven motion provides a calm contrast. It stands against the hectic activity of the urban environment. The artists aimed to create a collaboration with nature.
The sculpture’s form references the site’s brewery heritage. The circular ring recalls the brewing-vat supports. These were found in the decommissioned Brewery Yard building. The ring’s motion re-imagines the stirrings of brewing. It also reflects the tipsy effects of alcohol.
The components are made of carbon fiber. They are joined by stainless-steel connections. The turning speed depends on wind force. Engineers conducted wind tunnel tests. This helped them minimize materials while ensuring stability.
A special bearing unit allows for almost frictionless motion. It balances the ring’s weight. It enables the sculpture to move in winds as low as 2 km/h. Brakes are in place to dampen motion in high winds.
The Halo sculpture has a reflective pearlized glaze. This gives its surfaces a glistening glow. This effect was achieved after research with a color consultant.
The carbon fiber ring was fabricated at a boat building yard. Full-scale assembly and wind tests were conducted. The sculpture was completed in July 2012. The total cost was $1.3 million.
The Institution of Engineers Australia recognized Halo with the President’s Award. This award was given for innovative techniques in design and fabrication.
Halo stands as a symbol of artistry. It is a triumph of engineering. Its gentle movements invite contemplation. As the Halo turns in the breeze consider its blend of art and science. Think about its connection to this place. It is a captivating landmark in Sydney.
