Bringing together science, big data and audiovisual art, Ghost Trees offers a new way to connect to nature and reflect on our place within it – and our impacts on it.
Ghost Trees is a creative representation of big data sets, captured by the Terrestrial Ecosystem Research Network and transformed into an immersive experience by Australian artists James McGrath and Gary Sinclair. TERN used LIDAR (light detection and ranging) scanning to capture digital ‘memories’ of the endangered Rushworth Forest on the lands of the Ngurai-illam Wurrung people in Victoria. Environmental sensors generated three-dimensional scans for conversion into ‘point clouds’: data that represents disappearing landscapes.
Visual Director James McGrath transformed these point clouds into moving graphics, creating a visualisation entirely from real-world data without any artificially generated content. Audio Director Gary Sinclair studied eco-acoustic site recordings and generated melodic phrases from the spatial data points of the trees to give voice to the forest. The result is an ephemeral, artistic and deeply moving portrait of what we are losing from the world around us.
Ghost Trees at the NFSA includes the addition of a window into other Australian ecosystems hidden within the main installation. Using the 19th century ‘Pepper’s ghost’ illusion, the central pod creates a shadowy touchpoint with trees in the Botanic Gardens of Sydney, Tasmania’s Huon Valley and the TERN research SuperSite in the Snowy Mountains: semi-transparent whispers from other forests.

The making of Ghost Trees
Science, data and art come together in this ‘digital memory’ of an endangered forest.
Artist bios
- Nature as Data is an ongoing creative collaboration between James McGrath and Gary Sinclair.
- Their exploratory work continues to evolve and morph while retaining the core themes of data, environment, science and art.

James McGrath
James McGrath (pictured left) is an architect and painter. Over the past three decades, he has explored the meeting point between art, architecture, theatre and new media. He trained as a painter, assisting Patrick Betaudier (Paris) and Arthur Boyd (Australia). His work is motivated by the differences and tensions in the marriage of painting and 3D video. His digital installations and videos were commissioned by several Australian museums and subsequently presented at the Los Angeles J Paul Getty Museum in 2000. In 1999 and 2000, his work was included in the Sydney and New York film festivals. He has lectured in architecture at the University of New South Wales, where he was awarded the Australian Postgraduate Award. James has exhibited in New York, London, Sydney, Hong Kong, Toronto and Paris.
Gary Sinclair
Gary Sinclair (pictured right) is a music composer, sound designer and recording artist. Working in the museum, experiential, public art and broadcast sectors, he has established a multi-discipline practice Tactile Music. His work explores the liminal space where sound design and music reside, creating soundtracks referencing contemporary classical, minimalism, ambient and electronic music genres. Gary is committed to integrating traditional music production, field recordings and creative technology. The work is grounded in authentic science concepts and the natural world and morphs from the real to the abstract. His approach to music and sound is altruistic, allowing existing narratives within science, nature, technology and philosophy to directly inform the production of his soundtracks. Utilising contemporary techniques in data sonification, generative music and sound processing, he views his role as a guide or conduit for the sonic articulation of voiceless ideas.
