Ever have the desire to print out a text message in large dot matrix lettering on a wall? If so, Liat Segal from Sweet Tech Studio has the device for you. Comprised of seven servo actuated felt markers controlled by an Android handset via an IOIO board, the Cellular Wall Printer allows you to manually scroll text from SMS, Facebook, Twitter, etc. across a large flat surface in big dot matrix-looking type. [Thanks, Liat!]
