For use only with compatible desktop 4D Graphics Applications. Using a wireless network connection, this App replaces the desktop multibutton mouse controls for 4D rotations with the iPhone/iPod/iPad multifinger touch screen controls for 4D rotations implemented in the "4Dice" iOS App. Sample desktop Server code in C can be found in http://homes.soic.indiana.edu/hansona/4Dice/. This may not behave correctly on some local networks. This is under investigation.
