From Russia with Love comes this keyboard via Think Geek.

For the paltry sum of $1,589.99 you too can have a keyboard (Mac or PC!) that has a tiny OLED screen on each key.

Among the things this Keyboarde-Royale will do is play a Quicktime® movie on each key! Each key can change its image dynamically depending on what you’re doing. Hold down SHIFT and all keys go uppercase. Run Photoshop and you can set it so each hotkey has an image representing its function. Set a key to monitor your CPU usage or display what iTunes track you are currently playing. You can make a key into a tiny clock with moving hands and play animated gif files

Other things (among many) that you can do with it are:
Various System Monitor functions can dynamically display on a key including CPU usage, CPU temperature, Network Speed, and Memory Usage
Play a GIF animation or Quicktime movie on a Key
Paint images across all keys at once in your image editor of choice
Key sets can be linked to an application, so whenever you open that app the appropriate keys come up
Powerful layer function allows you to combine existing key sets in different ways
Use any language with the appropriate key images including Cyrillic, Ancient Greek, Georgian, Arabic, Quenya, and Hiragana.
Display notes, numerals, special symbols, HTML codes, math functions or any other special symbol.

Think about it, you can display your own photos on each key and have a mini-me museum of your art! It’s also a built in USB hub and has a SD Card Slot.

So, run your fingers over to Think Geek (click here) and be the first on your block (in your country?) to order one!
