WGBH News: A change is in the air on the South Shore as New Bedford hosts the first ever “Summer Winds” arts festival. Organized by the Massachusetts Design Art & Technology Institute, or DATMA, the festival was designed to highlight the city’s emergence in the wind turbine industry with several wind-themed public arts projects. Projects include “Silver Current,” a massive floating sculpture by Patrick Shearn of Poetic Kinetics, which features more than 40,000 silver streamers stretched across Custom House Square on a fishing net. “The quality of the intimate experience underneath is like … walking into some kind of like Hobbitville,” said Shearn. Most of the Summer Winds events are free to the public and continue all summer long.
