Floating on the raspberry patch fence and tumbling across the lawn, Richard Moffatt’s Orbs bend the irregular shapes of machinery into the round. Tessellations of intersecting triangles and lines ensue in a conversation of shapes, casting patterns below in their shadows.

Identification of the constitutive parts is essential: spade heads here, reinforcing rods there. Burnished and golden, remnants of the word “caterpillar” and flecks of yellow paint tell of one Orb’s past life as a digger. Elsewhere, clutch pads are clustered together like a giant dandelion gone to seed and ready to be blown away. On another Orb, closely interlocking hexagonal plates have been cut into a shape from a steel disk harrow and now fit together

like an armadillo’s shell. In contrast, the finer No.8 wire ball teeters on the edge of the raspberry patch, as a tumbleweed caught on a spur.

These Orbs form a constellation with the Snowy River Sphere on the Kosciuszko Road near the Snowy River Airport, and all recall the boulders strewn landscape of the region.
