Sixty Foot Falls stretched along a warehouse fence: blue turning to green, water turning to forest, as you drive past.

In the hills above the Kenwick warehouse site, in the Ellis Brook Valley, water drops sixty feet off the Darling Scarp and becomes a forest. Sixty Foot Falls is the City of Gosnells' most spectacular natural feature, offering sweeping views across Perth and a visceral experience of water's power, and at its base the cascade meets the earth and gives rise to the lush, vibrant bushland around it. Cascading captures that precise moment of transformation, water becoming nature, and stretches it twenty eight metres along the site's boundary fence.

The artwork tells the story in colour first. Three shades of blue carry the water: the deep, cool tones of the pools at the base of the falls, a mid blue, and the light, aerated blue of the cascade's spray. Three shades of green carry what the water sustains: the rich green of the eucalyptus canopy, the mid tones of the bush, and the bright green of new growth. The gradient flows along the length of the screen from blue into green, a visual story of transformation and symbiosis told at the pace of a passing car.

The form makes the water move. Vertical aluminium fins, each folded to one of six angles and painted on both faces, are arranged along the fence from an abstracted image of water ripples, and together they produce a shifting moiré that mimics falling water and the rustle of leaves in the wind. As you walk or drive past, the colours and the form flip, blue giving way to green and back again, so the fence performs its waterfall continuously for the street without a moving part or a watt of power.

There is a quiet rightness in the site pairing. A warehouse is itself a place of constant flow, goods arriving, transforming, moving on, and the artwork links that daily industrial current back to the fundamental natural force it echoes. The gesture is also deeply practical: the screen is the boundary fence, built as prefabricated modules on standard fence post logic, cored into the retaining wall like any garrison fence, so a required piece of infrastructure becomes the site's landmark at little more than the cost of making it beautiful.

At the entrance to an industrial estate, Cascading offers what the best of the studio's gateway works offer: a celebration of movement, energy and transformation, and a reminder that even here, the falls are just up the valley, still turning water into green.
