Verdox, for the sake of brevity. It is an open-source academic project, aiming for creating a full featured 3D adventure platforming game. It uses Bullet for physics, Ogre 3D for graphics, OpenAL for audio and Blender for artwork. It is not very fun to play yet, but you can wander through the level if you have the patience to build it.
It is being developed for some time by students from Universidade Federal de Uberlândia
, Brazil, and now is supported by a local technology company, CTBC
You can find some screenshots, the code and a video in http://www.games.facom.ufu.br/?p=verdox
Unfortunately, the website and most documentation are in Portuguese only, since not all students from here are proficient with English.
