Virtual reality has sparked many people's imaginations, but writing VR programs remains difficult. Besides the obvious problems of managing arcane I/O devices (trackers, gloves, and so on), the programs must allow the participant to operate effectively in the immersive environment. Virtual environments present a new medium for both the participant and the programmer/author. In the University of Virginia's User Interface Group, we believe the best way to accelerate development in a new medium such as VR is to provide tools that allow people without highly technical backgrounds to create programs for it. These novice authors must be able to quickly try different nuances of an idea. They must be able to easily ask "what if" questions. To support this goal, we are developing Alice, a rapid prototyping environment that can generate VR environments. The name "Alice" honors Lewis Carroll's heroine, who explored a rapidly changing, dynamic environment.>
