The design trick behind Erlich’s installation is child’s play: Build the facade of a building on flat ground, and then erect an enormous mirror standing perpendicular to it. The “building” is reflected, life-sized and standing-up, in the mirror. But because the physical facade is safely on the ground, anyone can walk around or lay down or otherwise playfully pose themselves on it, and look up to see themselves “stuck to” the mirror-building’s vertical surface.
Cheap trick? Maybe, but it’s the attention to detail writ large that makes Bâtiment feel more authentic than any digital simulation. . . . .
