A 3D-SciFi-Racer called H-Craft Championship . I've worked on this project together with Philipp using the Label irrgheist. It's a very fast-paced game, runs on Windows, Linux and Android and it's completely free by now.
Virtascend is a VR prototype. It offers
a 3D World that runs on Client+Server where people can meet, chat, view images together and can exchange files. It's also cross-plattform for Windows and Linux and can probably be ported easily to further
systems thanks to using the Irrlicht engine and the boost software libraries. Unfortunately it's unfinished and I don't own the rights, so it probably won't be open source anytime soon. For any info about it please get in contact with Vlastimil Kudrnac (info*at*virtascend.ch).
Stahlwurm A nice worm game for 1-2 player with graphics from G.C.Feser (aka TONG) from whom I've unfortunately heard nothing in a long time :-(
Fruit of the doom A homage to Wizard of Wor, it was a teamproject in the 1st semester at the FH-Furtwangen.
