I wonder if it would be possible to create something like a standard keyboard that was simply more flexible than the basic solid keyboard?

Keys could have their own inputs that fed back to the main board, which then acted like your standard keyboard setup. But the keys and their own inputs would be on wire or something else that could be stretched, and the shell of the board that everything sat in could be made of adjustable slides.

No idea if that would be more or less expensive than something like this.
