Wedding state-of-the-art VR technology with a deep appreciation for the systems and networks of the natural world, with particular focus on the plant kingdom, this immersive experience from Marshmellow Laser Feast plunges the spectator straight into the neural pathways of a forest scene, thrillingly casting off corporeal form. Outfitted in the somewhat cumbersome accoutrements of the technical gear (headset, rucksack, wristbands, heart monitor!), every breath now expelled in a visible wash of blue microbes, fellow viewers reduced to vascular silhouettes that float around you, a majestic Sequoia tree (considered to be the greatest organism in existence) anchors the central area of attention.
Throughout the 20-minute programme, you are encouraged (quite past the spectacle) to contemplate the human interaction with and connection to the essentially invisible but vital universe of nature, our dependence upon its magnificent processes and our often malignantly careless stewardship of its delicacy. Lifted out of our separate consciousness, now a buoyant gust of disembodied spirit, we inhabit a space where we are able to witness the abstract whirl and course of carbon dioxide and oxygen and feel as one with the respiration of the earth.
With imperceptible ease, the viewer rises along the tree, past its crown, until the final moments pass as a pleasant hallucination of nakedly biological pulsations-you emerge from the session with a happy awareness of having been broken down into your basic chemical components. At £20 a session, though, it is quite a dear education. We Live in an Ocean of Air continues at the Saatchi Gallery through 20 January
