Liquid Crystal Keyboard

First submission... hello everyone... I discovered that there are a lot of old backlit keyboard ideas, as well as the LEGO keyboard one, that are similar, but I'm hoping that mine qualifies as a new idea...

I would like a keyboard to have a small liquid crystal screen on each key, where the letters are. I am NOT talking about a touchscreen keypad, but a normal keyboard where you have the satisfaction of pressing down on each key with a thunk. The key screens display the usual key cues, like !/1, but when you change your keyboard setting to e.g. Cyrillic or Japanese, the displays change too. It is better than the Virtual Keyboard software display you get in Windows, which puts the keyboard layout on the screen so you have to look up and down for each keystroke.

To have mass market appeal, the keys would be backlit i.e. colored background, with predetermined colors (like the Empire State Building light display) linked to calendar/holidays, and with self-setting options as well. You can put a background image on your whole keyboard or on each key. You can have a Keyboard Screensaver. You can make it flash to music. You can make the letters larger for people with poor eyesight - the shift key will change the keys to the shifted capitals so you know before you type.

The reason I thought of this was, I had to type in Cyrillic and it took me a key-by-key search to find their A. So, what would also be really good is to have the key display respond to voice commands - e.g. if you are new to the American keyboard and can't find the @, there will be a software where you yell "At!" at the computer and the key blinks at you. This will encourage new developments in learning-to-type software with blinking keys, and maybe the silly paper clip Office Assistant can teach you one shortcut command key combination per day.

I would like to see this on cell phones as well, especially for the Composer. I always forget which keys make the notes an octave higher, etc. When I go to the Composer setting, the key display would also change. I guess this can be applied to text messaging as well, although I am a cell phone novice and wouldn't really know.
