Have you considered doing this for mice? Im fine with a normal keyboard, but mice, maaaaan. My hand doesnt sit right on any mouse, and my hand is always dragging on the pad, etc.

I briefly thought about like a form fitting style, where you go and have your hand scanned in resting position on a dummy mouse, and then the mouse body is formed for your hand. This could also allow for button customizations as well.
