Could be the BrixMed API, the sample application was called the Dexterity Game. Written by Ngh Hern and Luis Serra at KRDL in Singapore as a demonstration for their API. Actually that is using something called: Dextroscope (formerly Virtual WorkBench). http://www.krdl.org.sg/RND/biomed/dextroscope/index.html > > Another sort-of side question would be how well immersive VR systems > compare with standard windows interfaces.
