 Hey, this is Sam Bifer with The Verge and I'm here at the Samsung booth at CES and they have reinvented the window. So this is their transparent smart window prototype and it actually runs on ambient lighting so the LCD is powered by the sunlight outside. As you can see they've got prototypes of office programs, you can get flight information, stuff like that, a whole bunch of that. into pack. So of course, that's my idea of ambient lighting, the light just doesn't work so well, so the night mode seems to reverse the colors so you can use it at the time of the day.
