tific Communications and Media Systems at the National Center for Supercomputing Applications. Ms. Cox has exhibited computer images and animations in more than 100 invitational and juried exhibits during the past nine years, including shows at the Bronx Museum of Art in New York, the Everson Art Museum in New York, the Feature Gallery in Chicago, the Feature Gallery in New York City, the Fermilab in Chicago, and the Museum of Contemporary Photography in Chicago. She has authored many juried papers on computer graphics and scientific visualization and received the Coler-Maxwell Medal for Excellence in 1989. Her work has been reviewed or cited in more than 75 publications, including Time, National Geographic, Wall Street Journal, and IEEE Computer Graphics and Applications. Ms. Cox spent a sabbatical working on an IMAX film, Cosmic Voyage, for the Smithsonian Institution's National Air and Space Museum. As associate producer for scientific visualization and art director, she has orchestrated scientific visualization software, data, and design for Pixar Animation Studios, Santa Barbara Studios, Princeton University, the University of California at Santa Cruz, the San Diego Supercomputer Center, and the National Center for Supercomputing Applications. Ms. Cox received an M.F.A. in computer graphic arts and a B.A. from from the University of Wisconsin-Madison.

WARREN J. KATZ is vice president and cofounder of MäK Technologies. His responsibilities include corporate operations, new business development, and program management. MäK's corporate goal is to provide cutting-edge research and development services to the Department of Defense in the areas of distributed interactive simulation (DIS) and networked virtual reality (VR) systems and to convert the results of this research into commercial products for the entertainment and industrial markets. MäK's first commercial product, the VR-Linkä developer's toolkit, is the most widely used commercial DIS interface in the world. It is an application programmer's toolkit that makes possible networking of distributed simulations and VR systems. The toolkit complies with the Defense Department's DIS protocol, enabling multiple participants to interact in real time via low-bandwidth network connections. VR-Link is designed for easy integration with existing and new simulations, VR systems, and games. From June 1987 to October 1990, Mr. Katz worked for Bolt, Beranek, and Newman on the SIMNET project. He was the resident drive-train simulation expert, responsible for mathematical modeling of the physical systems and software development. Mr. Katz received B.S. degrees in mechanical engineering and electrical engineering from the Massachusetts Institute of Technology.
