"Our new waveguide uses billions of invisibly small nanostructures, so small that more than 10,000 can fit on the tip of a single hair. SPECS use the same advanced technology found in Boeing 787 Dreamliner windows, so the electrochromic lenses gently shift from clear to tinted in just 10 seconds."

This sounds slightly like Texas Instruments DLP (digital light processing) in that there's something actually physically moving. Does anyone have any more info about what this actually is?
