What is a CAVE Good For?

ynakai asks: "Today, I had the fortune to be allowed to play with demo applications in a CAVE. This technology is stunning, but what is the killer app? A staffer said that despite the potential use as a teaching tool for medical students, the system is rarely used now except by digital artists (who admittedly create some stunning experiences - try the VRML versions of some). Surely Slashdot can think up better ways to make use of a multimillion dollar room of fully immersive 3D interaction, besides FPS games?"
