There's something so much more personal about receiving a hand-written letter as opposed to a typed message, and the Cadmus Digital Pen aims to bring back the sentimentality of older correspondence methods by updating them with cutting-edge technologies.
Designer Fred Ingleby proposes an intelligent system by which the author can employ a classic fountain pen tip, or the more modern ballpoint pen as his choice stylus. These inky ends are designed to fit snugly into a hi-tech handle which has an Anoto optical scanner built-in, which records words as you put them to paper.
Each apparatus has an internal hard drive and a unique email address associated with it, so that once you've completed a letter, the lines that you wrote and copied with the Cadmus Digital Pen scanned will be delivered digitally redrawn to your recipient.
