Brendan tipped us off – The Optimus Maximus dynamic display keyboard is available for ownership, a steal @ only $1,589.99 (!) –

As you should know by now this amazing keyboard features a tiny screen on each key… that’s 113 screens in all. What can you do with these tiny screens you ask? Well each key can change it’s image dynamically depending on what you doing. Hold down SHIFT and all keys go uppercase. Run Photoshop and you can set it so each hotkey has an image representing it’s function.

Sounds like you’d be stuck designing the key/image layout for most apps – but at that price, you may just pay someone else to do it for you
