Bilateral Time Slicer
Bilateral Time Slicer
2016
A biometric tracking system finds the axis of symmetry of members of the public and splits a live camera image into two slices. With each new participant time slices are recorded and pushed aside. When no one is viewing the work, the slices close and rejoin creating a procession of past recordings. View Details.
Call on Water
Call on Water
2016
Call on Water is a fountain that writes words in mid-air with plumes of cold vapour that ascend from a water basin. Dozens of poems by Mexican writer Octavio Paz are presented which describe readable air, the moment when the written word is spoken and becomes the atmosphere itself. The poems’ content becomes tangible briefly, almost breathable, then disappears in turbulence. View Details.
Pulse Corniche
Pulse Corniche
Relational Architecture 22, 2015
Pulse Corniche was an interactive canopy of powerful light beams projected into to the sky by robotic searchlights whose brightness and orientation was controlled by the heart-rate of visitors to the Abu Dhabi’s Corniche. People were free to participate by holding a sensor placed in the centre of the plaza that converted the electrical activity of their heart into a unique lighting sequence. The intensity and direction of the lights visualized the different biometric rhythms of each participant, in an urban scale. View Details.
Airborne Projection
Airborne Projection
Relational Architecture 20, 2013
“Airborne” was an interactive installation commissioned by the Chrysler Museum of Art to transform Norfolk’s public space into a poetic shadow play. Participants blocked the light of two projectors casting their shadows on a 900 sqm wall, and these were tracked by computerized surveillance systems. Out of the shadows emanated bellowing smoke which was mapped onto the wall and accumulated in it. Readable within the smoke were clouds of text, themselves turbulent, from salient poetic texts on light and shadow. View Details.

Articulated Intersect
Relational Architecture 18, 2011
“Articulated Intersect” is a large-scale installation that produces an interactive canopy of light that can be modified by the public using six large lever-controllers that protrude from the ground. As a participant points one of these levers three powerful robotic searchlights automatically intersect in the sky to create an apex at that location. The participant may direct the apex anywhere over the city in real-time, creating an animated tetrahedron inspired by the work of Richard Buckminster Fuller. View Details.
Sandbox
Sandbox
Relational Architecture 17, 2010
Sandbox is a large-scale interactive installation created originally for Glow Santa Monica. The piece consists of two small sandboxes where one can see tiny projections of people who are at the beach. As participants reach out to touch these small ghosts, a camera detects their hands and relays them live to two of the world's brightest projectors, which hang from a boom lift and which project the hands over 8,000 square feet of beach. In this way people share three scales: the tiny sandbox images, the real human scale and the monstrous scale of special effects. View Details.
Solar Equation
Solar Equation
Relational Architecture 16, 2010
"Solar Equation" is a large-scale public art installation that consists of a faithful simulation of the Sun, 100 million times smaller than the real thing. Commissioned by the Light in Winter Festival in Melbourne, the piece features the world’s largest spherical balloon, custom-manufactured for the project, which is tethered over Federation Square and animated using five projectors. The solar animation on the balloon is generated by live mathematical equations that simulate the turbulence, flares and sunspots that can be seen on the surface of the Sun. This produces a constantly changing display that never repeats itself, giving viewers a glimpse of the majestic phenomena that are observable at the solar surface and that only relatively recent advances in astronomy have discovered. Using an iPhone, iPod touch or iPad, people may disturb the animations in real-time and select different fluid dynamic visualizations. View Details.

An interactive installation featuring powerful robotic searchlights that create static columns of light in a dark room. When someone tries to walk into a light beam, a computer automatically moves the searchlight so that the beam is pointed somewhere else on the room. A video tracking system observes the room and makes sure that the lights are always illuminating empty spaces where there is no one. People may continually attempt to enter the spotlight but the system will adapt to ensure this can never be achieved. View Details.
Less Than Three
Less Than Three
2008
"Less than Three" is an interactive installation of light strips that form a network between two intercoms. As a participant speaks into an intercom, their voice is translated into corresponding flashes of light and this light pattern is transmitted visually along one of the several possible pathways through the network. When it reaches the other side, the viewer's phrase is once again released as sound. Several voices can be carried simultaneously and the short contributions going fast through the network and the longer ones taking longer. View Details.

1,000 Platitudes is a large-scale photographic intervention project. It is comprised of photomontages and a video with 1,000 words or expressions commonly used to promote globalised cities to potential investors, such as "open", "modern", "clean", "multicultural" and "cosmopolitan", for example. To make these images, a powerful projector (110,000 ANSI lumens of intensity for images of up to 70 x 70 metres) was placed on a 12-ton truck with a generator. View Details.
Two Origins
Two Origins
Relational Architecture 7, 2002
In this intervention the emblematic Place du Capitole in Toulouse was transformed by a projection of The Book of Two Origins, a 13th-century heretical manuscript compiling the theological beliefs of the dualist cathars. Once a vibrant community in several regions of Europe, the believers in the two origins of the Universe were virtually annihilated by the brutal crusades that gave birth to the Inquisition and France's expansion. The texts are illegible since they are projected overlapping each other on the same façade from two distant projectors; only when passers-by block one text with their bodies is it possible to read the other text inside their shadow.
