Back in January, in an entry on façades, I noted a recent, and relatively local, favourite - the extraordinary western face of the Brisbane Girls Grammar School Creative Learning Centre. Brisbane buildings have to posess a trick or two to deal with the fierce sun on their western side, and local firm m3architecture obliged with a protective layer of anodised aluminium slats, overlaid onto a wall painted with black and white stripes ... which just happens to create a gigantic moiré effect as you move past it.
The school sits on a hill adjacent to the six-lane Inner City Bypass, and so commuters witness the entire six-storey façade undulating and revolving as they drive past. In my earlier post I promised a video of the thing in action and I'm yet to deliver, but in visiting the excellent (and aforementioned) 'Place Makers' exhibition at the Gallery of Modern Art in Brisbane recently, I captured the next best thing - some rough videos of the exhibition's simplified 1:11 scale model of the western wall.
That is essentially exactly what it looks like, just 1:11 scale. The moiré effect is surprisingly simple, as this close up of the model indicates. (For the curious Wikipedia's definition of the moiré is worth a read.)
Some photos of the model at 'Place Makers', which is also simple but a very effective display.
Some images from an Architecture Australia article, indicating what it looks like in context:
m3 produced some notes on their design for the building on their website, though they don't reveal much detail about the provenance of the moiré idea - except perhaps in the phrase "dynamic space of circulation". I half-wonder whether the feathers of local parrots or the ubiquitous slats and blinds of Queenslanders' verandahs may have provided subconscious inspration.
