18. Building Projections
International / Various
Building projections as an art form gained traction in the late 1970s with artists such as Krzysztof Wodiczko and Jenny Holzer creating seminal works that brought the idea of public art to a massive urban scale. New technology has reinvigorated the potential of enlivening a public space by projecting moving images onto static buildings. For example, a drab wall is electrified by a dazzling light display triggered by passing car traffic, or passersby’s text messages replace a classical façade’s carved inscription with citizen proclamations. Architects have been experimenting with programmable façades for years, and dozens of cities worldwide host Nuit Blanches, all-night festivals featuring a range of illuminating public interventions.
