An article at ZDnet about the Iowa State C6 virtual reality room:

The equipment in this room has not been updated in six years. But with money from the Air Force Office of Scientific Research, the C6, which is operated by the Virtual Reality Applications Center (VRAC), will receive new equipment this year for a grand opening in 2007.

The difference between the equipment currently in the C6 and the updated technology to be installed this summer, "is like putting on your glasses in the morning," said James Oliver, the director of Iowa State's Virtual Reality Applications Center and a professor of mechanical engineering.

The new equipment — a Hewlett-Packard computer featuring 96 graphics processing units, 24 Sony digital projectors, an eight-channel audio system and ultrasonic motion tracking technology — will be installed by Fakespace Systems Inc. of Marshalltown.
