Tom Dixon says Etch was inspired by the logic of pure mathematics. Even without knowing that backstory, the striking geodesic form speaks volumes on its own. Composed of ultra-fine perforated metal sheets, the pendant light's angled surface casts atmospheric shadows. Tom borrows the industrial photo-etching process used to produce electronics to create the intricate patterns on the fixture's surface. Yet another example of the cleverly coherent design sense of this much-lauded British maestro.
