 Can you open it? This is just a prototype. The network is kind of bogged down right now. So just a transparent piece of glass here and then you're basically touching the top of that screen. This acts as a touch screen. It's basically a touch pad and a touch panel at the same time. And that overlays the top of the screen when you close it? When I close the screen, I'm touching through it, so to speak.
