Thank you to Paula and Madison for believing in me more than myself, Susan Henderson, Saeeda Hafiz, and Jesse Schell for their unwitting inspiration, and students past and present for providing an endless source of motivation.
To my HU and ETC families, especially Ralph, Don, Eric, and Bili, thanks for taking a chance and being supportive.
Special thanks to Tyler Batts, who's programming skills brought this project to life.

John Williamson has worked in VR since 1995. As a producer/designer, he has shipped over three dozen games (America’s Army, Hawken, SAW, and Spec Ops) in nearly every genre (RTS, FPS, Arcade, Simulation, Survival Horror) on nearly every platform (iOS, Android, Wii, PlayStation, Xbox, web, PC, and VR). He is also an award-winning filmmaker and has taught game design at DigiPen and Harrisburg University. Now, he works in VR, creating immersive training for a wide range of high-consequence trainers for the US Air Force, Army, and NASA.

I would like to thank my wife and daughter for their patience, Dr. Tom Furness and Capt. T.K. Treadwell for their VR inspiration, my parents for giving the option to explore games and VR for a living at an early age, and my students for helping keep me young.
