Um. This is AMAZING and, as MOMA design guru Paola Antonelli put it, “I want to go to there.” The Guardian’s Oliver Wainwright visits a new installation at the Barbican in London, where visitors get to walk through a torrential downpour without getting in the slightest bit wet. Love the comment from one of the creators, Stuart Wood of the collective Random International, as he grapples with the perennial art vs design conundrum. “No would-be designer would create something that’s completely pointless,” he says, justifying his self-description as artist. That’s as maybe, but I for one find this type of installation far from pointless. Magical, in fact.
