This structure on the campus of Iowa State University in Ames houses C-6 technology for virtual imaging-the first in the world. Neumann Brothers built this two-story structure within Howe Hall on campus. It consisted of a sloped ellipse with structural steel and fiberglass plastic skeleton, and an exterior skin of metal/acrylic panels on different stand-off dimensions. Structural studs used in the project were custom-designed and fabricated using CAD technology. The project was selected as one of the top three national projects by National Council of Structural Engineers Associates and won the merit award. With this as its focal point, ISU hosted the first international virtual reality symposium in June 2000.
