Update on Optimus Keyboard

I've always wonder what kind of connector is going to be used in Optimus keyboard. Because I've assumed the screen will have to move along with key when it's pressed. Which leads me to believe connector will easily wear out. Their project page says

The main idea behind the Optimus Maximus key design is that the part with the display is fixed, while the transparent cap is moving, pressing a Cherry switch underneath (patent pending :-).

I've never have think of that idea. Although the image on the key might be distorted due to transparent key-cap being separated from the screen.
