The portals artwork concept draws on the familiar Australian image of the wispy fronds of the Casuarina tree, one of the dominant tree species on the pre airport site.

By distributing the abstracted graphic around the portals the visitor is given a sense of passing through or under this overhead Casuarina canopy.

The abstracted frond pattern is lasercut into a linished stainless steel surface, each cut-out subsequently sealed from behind with an acrylic diffuser panel. An LED colour mixing system (red /amber) gives a continuously variable colour shift across the pattern such that the colour of any particular section of the Casuarina pattern depends upon where the cut-out sits with respect to the colour mix.

The intensity of glow from the artwork is directly proportional to the surrounding light level such that the subtlety of daytime effect contrasts dramatically with the night time experience.
