Wow a PC Gun that actually follows your movements....hmm are there any manufacturers selling this type of thing to PC gamers?
http://www.gossipgamers.com/the-coolest-pc-game-gun-mod/Get ready to ejaculate as you feast your eyes on this new mod known as the PC VR Game Gun. You can now get your lazy a** off the couch and get in some real live action. Can you say, real life video game simulation? Perhaps Project Natal and Nintendo can learn a thing or two here.
Some features include low-cost, dual-axis miniature rate gyroscope that is fully self-contained for easy integration into human input devices such as the PC VR Gamegun. A unique electromagnetic transducer design and a single etched beam structure utilize the Coriolis effect to sense rotation in two axes simultaneously. Operating between 2.3 and 3.6 volts. 1K of available EEPROM storage on board. Low drift.
Full Motion Tracking - Move the gun and it moves the mouse.
