WYSIWYG. The name stands for "what you see is what you get." It is a lighting visualization program that allows you to see what light will do. Among its many features: you can connect to a lighting control board and use the board to control the simulations. Additionally, WYSIWYG will simulate moving lights in real-time. There is a student version available for around $300. This student license expires after one year.
