Fortress Productions was a short-lived programming group for the TI-83+ and TI-86 graphing calculators. They released a few notable games and programs, in addition to an optimization guide for TI-Basic and assembly respectively. The guides included optimizations to conserve both time and memory, as well as general shortcuts that programmers can employ in their programs and games. They also had some interesting projects under development including a customizable periodic table, an in-depth matrix solver that is a full-fledged Flash application, and a drawing utility program to manipulate pictures on your calculator.
