What if people would expose and visualize their SMS text messages on buildings? If your Facebook status would be printed on a real, physical wall? What if you really checked in when you check in?
The wall printer takes the wall status concept back to physical dimensions.
Inspired by old-school pin printers, the wall printer is a manually held device using seven markers to print digital messages on any flat surface. 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.
Connected to a cell phone, the printer can be directly fed by SMS text messages, Facebook statuses, GPS coordinates or practically by any other digital data source.
It uses a IOIO board to connect the physical electronic parts to an Android device and control them from an Android application.
