The installation takes the form of a telescope, installed near a window in the gallery space. Participants are invited to take the role of Jeff in the film, observing and scrutinizing the neighbours and neighbourhood of the gallery. However, the image through the telescope does not wholly coincide with what is seen by the naked eye. Instead, utilizing augmented reality techniques, portions of the image are replaced. Specifically, windows of neighbouring buildings become silver screens, presenting participants with footage from Hollywood films which utilize the Rear Window cliché.
Now, I'm too much a techie to understand their motivation in creating such an installation, but I do like the idea. Read more about it on Mike Lawrie's site.
