KermMartian writes "In an effort to make your trusty graphing calculator more like a computer, a shell called Doors CS has been developed, with an integrated networking stack, CALCnet2.2. The protocol is demonstrated in a nine-calculator pong-type demo, and the many file management, GUI, and other features of Doors CS can be seen at here. All the associated software is available for download."
