Remember the Optimus, right? A keyboard with a screen for each key, thus allowing for full customization, changing layout, displaying icons, and so on. But in the end, it never got out. Only ever-delayed.
The concurrence may finally be out: an Australian company answers to the Russian concept with something similar, using e-Ink instead of more traditional screens.

Backlit, customizable, … Just fine…
I wanted an adapter in order to use always the same keyboard (thought of a Das Keyboard or a Code keyboard when they make them as AZERTY), but this could be an alternative solution too.
