Strange things happen when you get two designers collaborating. Case in point: Yuri Suzuki and Oscar Diaz teamed up to make the rec & play pens. These devices allow a person to “record” a drawing using a special type of ink (and the record pen), and then play the drawing back as a sound using the playback pen. The recording pen actually uses ink that is similar in composition to cassette tapes, meaning that you can record a drawing, and then play it back over and over again. I’d consider this to more of an experiment showing the convergence of sight and sound, rather then anything practical. If you want to see the pens in person, they’ll be on display at the kk outlet in London starting on September 3rd.
