Designer and Project Runway Season 2 alum Diana Eng has taken techy to adorable with her Twinkle Dresses. Showcased at the spring 2010 Mercedes Benz fashion week, Eng's line included a parade of whimsical summer dresses embroidered with LED lights. The wow factor: Sewn into the designs are tiny, voice-activated microphones, giving the wearer the ability to literally light up the room anytime she opens her mouth.
