The MacWood Keyboard is a set of wooden keytops you can place on your Mac’s actual keys. (The keytops apply with an adhesive that is, according to the company, “easily removable and leaves no residue behind.) The set comes in rosewood or bamboo, and can be ordered with or without cutouts that allow your keys’ backlighting to shin through.
