TiCube3D is a very basic and simple but effective 3D cube animation demo for the TI-89 and TI-92 calculators from Texas Instruments. It is written in C using the TIGCC cross compiler for GNU/Linux. TiCube3D is based on ddd which is based on stars3d. The TiCube3D-0.1.zip file comes with full source code and precompiled binaries for TI-89 and TI-92.
