This is one of the coolest homemade mods I've seen recently for gaming consoles. It really has the potential to revolutionize First Person Shooters like they are now. This mod consists of a 7" display and a few gyros mounted on top of a regular console weapon. The result is simply awesome. Enjoy!

Here's a cool electric gyroscope, that you could probably build at home. It's very simple, and yet it works amazingly well. Have a look!
