Yamaha's Prototype— Notebook?

Engadget posted something beautiful today. Showcased in the 2008 Yamaha design exhibition at the Milano Salone trade fair in Italy, this gem of a lyrics notebook (that's what I'd use it for), looks like something that would be really enjoyed by artists who need to have the keyboard nearby to work out ideas... only this one works on the Moon too. There is an incredibly cool site on Yamaha (called Key For You) showcasing some truly amazing designs - instrument designs among other things.
