Tesseract Trainer is a demo that displays a tesseract (the four-dimensional hypercube, analogue of the three-dimensional cube) as a 2D image, or viewable as a 3D image using a method similar to that one for viewing stereograms. Although it contains shareware functionality (“Unregistered” is displayed in the corner, and a registration code ($8) request appears after some time of continuous running), the source code is available under a GPLv2-compatible license (apparently public domain except for the reused parts like GLUT). It is written in C++, and the latest version is 0.1.4, released on 2005-06-09. It used GLUT, SDL, among other libraries.
