'Nature's Geometry' was the conceptual framework used by sculptor Greg Johns in creating a five-metre high structure that uses interlinking geometric shapes to demonstrate nature's micro-macro links and the importance of respecting and protecting them.

The distinctive sculpture is the latest addition to the Sculpture Down the Lachlan trail; a public art trail stretching 100 kilometres between Forbes and Condobolin NSW, along the meandering Lachlan River.

The three-tonne geometric piece was constructed in collaboration with boilermaker Darryl McFarlane of Demill Engineering using hundreds of solid 25mm mild steel units, each cut from solid steel plate.

"When links are broken, such as the extinction of particular flora or fauna, the whole system becomes vulnerable and can ultimately collapse," said Greg.

"The public can see through the form to the surrounding landscape, and this connection to the surrounding landscape is important," said Greg.

Formed from open hexagonal units, the sculpture offers vastly different patterns when viewed from different angles.

"When you move around the sculpture, which continually changes visually, a negative figure suddenly appears from one angle. The intended implication of the organic pod form is of a protective spirit. A deep, profound guardianship of place as a priority is a message this sculpture hopefully conveys."

Forbes Art Society's Chairperson, Trudy Mallick said the sculpture's connection to the landscape is complementary to the theme of environmental sustainability that spans across the trail.

"The illusionistic geometry encourages engagement, interaction and curiosity. Although made from steel, the sculpture somehow embodies the qualities of softness, flexibility and fluidity – which is in harmony to the natural environment," she said.

Lachlan Shire Council Mayor, Cr John Medcalf OAM welcomed the new addition to the Sculpture Down the Lachlan Trail, praising it's unique concept and craftmanship.

"Art should inspire us," he said "and Within-Without (of land and spirit) does just that. Greg's work adds another dimension to the award-winning Sculpture Down the Lachlan Trail and is a welcome addition to our region's cultural tourism offering."

The sculpture trail is part of the $7.2 million 'Boosting the Lachlan Valley Economy Art Project' and is proudly funded by the NSW Government's Regional Growth – Environment and Tourism Fund, the Forbes Art Society, Forbes Shire Council, Lachlan Shire Council and Evolution Mining.

Within-Without (Of Land and Spirit) by Greg Johns is located on Marsden Road within the Lachlan Shire and is designed to encourage travellers to pause and consider the patterns formed in nature and the interconnection that exists between them.
