When Nest CEO Tony Fadell took over Google Glass back in February, he pledged toredesign the headset "from scratch." Well, it looks like that process is well underway. In a company meeting today, Luxottica CEO Massimo Vian said the Italian eyewear company is working with the folks in Mountain View on not one, but two new versions of the device. Luxottica owns brands Ray-Ban and Oakley, and if you'll recall, the company worked with Google on frames for the original version of Glass.
