Normally, I would kind of skim through items like these and not think twice but
check out this guy's work on creating a PC game gun that acts like a head tracking unit using a toy gun from Walmart, gyro mouse, and a few other parts. It has a mounted LCD panel so it acts like your field of vision when you look down the barrel of the gun. You can watch it move around on the monitor in the background that mirrors what the guy see's on the LCD screen. Talk about a nice little project.
