The new AMC series Dispatches From Elsewhere was inspired by a massive art project created by the Oaklandish founder. Before it premiered last Sunday, months of promotional teasers for the AMC series Dispatches From Elsewhere intrigued viewers with scintillating visuals emerging from mundane settings, while only hinting at the show's quixotic premise. AMC describes its 10-hour series as the story of four people "brought together by chance — or perhaps it's by design — when they stumble onto a puzzle hiding just behind the veil of everyday life."…
