Broadway Overpass

View MoreLess

As part of the third installation of Unlooping the Loop, lighting artist Derek Porter proposed weaving light, color, and varying sizes of stainless steel mesh to create a pedestrian guardrail that, at dusk, comes to life as a lively moiré! This low tech graphic animation strategy creates an endless loop of patterns and movement, all dependent on the vantage point of the viewer. The graphic display unfolds slowly as a series of stills while walking, but transforms to an active set of shifting hatches at driving speed. From the interstate below, the moiré patterns take shape as an illusion at urban scale, creating a dynamic gateway to the city from Interstate 670.
