»Legacy« (2005) is a 21-foot-long rainbow made of cast street sweepings that emerges from a planter on MetroTech Commons in Brooklyn. The rainbow’s seven bands range in tone from brown to gray, and are flecked with color. They are cast from actual debris collected on seven consecutive days by the city’s street sweeping machines: dirt, grit, gravel, gum wrappers, bottle caps, socks, plastic combs, and whatever other litter the sweeper picked up during the course of a day. There is a small bronze beard that appears to be crawling out of the hole in the ground where the rainbow emerges. By Corin Hewitt.
