Oree makes wooden computer peripherals, and not just the usual keyboard and iPhone cases: also offered are matching touchpads (with optional numpad engraving) and "pebbles"–a gadget that combines a speaker and a wireless phone charger. Everything's offered in maple and walnut, with various engraving options.
The keyboard alone isn't unreasonable at $150, but a set seems terribly expensive: you're looking at $500 shipped!
