Commuters and holidaymakers anxiously pondering the impact of Brexit as they head to the Eurostar may welcome the distraction of Ron Arad’s shiny new sculpture for London’s St Pancras International station. The Israeli designer, architect and Royal Academician has dangled an 18m-long rotating aluminium blade from the vast transport hub roof as part of Terrace Wires, the station’s public art programme. Thought of Train of Thought—the second in a four-year series of commissions by the Royal Academy of Arts and station owners HS1—will be on show until January 2017. The work’s “hypnotic effect is greater than the means, so will hopefully be the delight of the public at St Pancras”, Arad says.
