It's not clear if Icelandic game studio CCP is extending its crazy MMO, EVE Online, into the world of virtualreality, but the company is working on some form of EVE-based VR application using the Oculus Rift.
The company is also (without DFKI) developing a virtualreality environment that uses a pair of active-shutter glasses and a head-tracking camera to let you wander around cave-like structures from the comfort of the lab.
