Visually simulating the spread of vegetation fires has advanced far beyond the four overhead projector system we used to use at Descanso Station in southern California. The system described in the video below from KOB.com uses a projector connected to a computer to place an image on a sand table, resulting in an amazing three dimensional background on which to simulate the spread of fires. Check out this video.
