The mockup image looks like a hoax, but it isn't. SenseSurface is a prototype system that lets you connect real knobs and sliders to any LCD screen. An x/y sensor matrix clips onto the back of the screen and attaches by USB. The sensor can pickup the position and movement of knobs attached to the screen (it's not clear how they're attached, but even a suction cup might work OK). The first prototype video shows the proof of concept. There are lots of questions (How do you close your laptop when it's covered in knobs?), but it's a nice idea - you could buy a cheap 19" second monitor and cover it in these things...
