There are plenty of extravagant desk accessories out there, but this one is at the very peak. Jaquet Droz has created a complex, 585-part automaton that can write your signature for you. The Signing Machine took four years of development and each one is fully assembled and finished by hand. Once your signature is programmed into the Signing Machine, its user must enter a four-digit code to unlock the device for it to be enabled. Owners can also request their own design elements, which will be done by hand at their workshops.
