Quick update on the Optimus Keyboard project: the OLED keys won't actually move. Instead, a transparent cover over the little screens will press down, keeping the screens fixed in place underneath.
This makes the keyboard seem even less interesting than it was before, and it's gotten down to pretty uninteresting levels at this point. Next they'll announce that rather than OLED screens, the keys will be very small flipbooks.
