The "Switcher" was an experimental interactive menu system for VR applications at the VRAC. It was a sort of VR operating system layer built on VR Juggler. The core functionality of this system was designed and implemented by Josh Brown. Andres Reinot and I implemented an instance of Josh's switcher framework: the "Cityscape Switcher." All artwork in the Cityscape was created by Josh Larson.
In the Cityscape Switcher, a miniature planet is populated by a tiny city skyline where each building represents a distinct VR application. When a building (application) is selected, the building explodes, the Cityscape fades out, and the application fades in. Later, quitting the application returns the user to the Cityscape.
