Researchers at Idaho State University are working on a virtual reality world they hope will eventually help emergency services professionals prepare for catastrophes. Ramesh Ramloll has created a small town as part of his ''Play to Train'' program that includes a residential area, presentation hall, police station and hospital. Participants can set up ''avatars'' who can participate in training exercises. Play2Train allows those setting up training scenarios to add weather events such as snowfall, rain and lightning. Simulation has long been known to be an effective training tool, nice to see it being used more and more.
