Created by artist Tyree Callahan, this ordinary looking typewriter with an extraordinary function. The ‘Chromatic Typewriter’ prototype uses a variety of different colors dispensed with each unique key rather than the traditional letters found on a regular typewriter. Even though it is just a prototype, Callahan has already put the typewriter up for sale, pricing it at around $3,000-$5,000. Further information can be found on Callahan’s website.
