We’re about halfway through the Mercedez-Benz Fashion Week here in New York, which often doesn’t have all that much of interest for us. But at the Diane Von Furstenberg show over the weekend, a special appearance by Google’s most sci-fi creation made us take notice. Select models wore Google’s Glasses, that crazy augmented-reality eyewear, as did Von Furstenberg herself and Google’s Sergey Brin, who sat in the front row. The models were filming a short documentary, to be called “DVF Through Glass,” which will be available to watch on Thursday.
