Back in January, when we first began contemplating how we would program Noho Design District — the just-completed four-day design extravaganza produced and curated by Sight Unseen and held in conjunction with New York’s ICFF — one thing was clear: Come hell or high water, we’d find a way to pull off an exhibition we’d been obsessing over for months, ever since the re-release last summer of the 1966 Bruno Munari classic Design As Art. Among the late Italian designer’s musings, photos, diagrams, and sketches, we were reminded of his childlike fascination with hanging mobiles — or as he calls them, useless machines.
