Whilst surfing the web today I ran across this pretty smart product: the Optimus keyboard. It's just a keyboard to plug into a computer... but with additional features. It is made with organic light-emitting diodes (OLED) on every key. This makes possible to actually draw any symbol on the keys, allowing to have different layouts with the same physical peripheral:

Are you a Quake player? You can set up the Quake layout too:

The keyboard is also equipped with additional keys which can be mapped to be shortcuts to produce any sequence (either write a string or execute a command in the system). The cool thing is that the keyboard will be OS-independent and open source, sold along with the SDK to program the interface. It should be launched in summer 2006 and cost ``less than a good mobile phone'' (as said by the producer).
