Boston public broadcaster WGBH has a new home. “This is the first serious example in Boston of a kind of architecture we’re beginning to see elsewhere, in Times Square, for example, in which the architectural façade of a building is no longer made of the traditional brick, stone, steel or glass but is, instead, an ever-changing, programmable image. Call it digital architecture. Architecture and media become one… That nightmare, though, is in the future, and for now, here at WGBH, digital architecture looks pretty good.”
