Cellular Wall Printer by Sweet Tech Studio

Inspired by old-school pin printers ,the Cellular Wall Printer by Sweet Tech Studio allows you to manually scroll text from SMS, Facebook, Twitter, etc. across a large flat surface in big dot matrix-looking type. Seven individually controlled servo motors move the markers up and down, drawing dots and dashes. When you manually slide the printer over a wall, the servo motions are carefully timed to produce text messages.
