Sixaxis Gun Mod
One DIYer takes his shooter control system extremely seriously. The owner and operator of MOE Productions created a hybrid PS3 Sixaxis controller inside of a plastic gun casing made by Namco. The result is a controller with all of the ease of control of a normal setup, but it looks way more badass when you're dropping headshots in BlOps.
A video of the entire process of modding the PS3 controller into a gun reveals that it's much more complicated than it might seem. The modder, who introduces himself as NetMoe in the video, had to disengage all of the contacts from the controller parts and re-solder them in the new casing.
I'm not too sure if the ergonomics of holding a gun are inherently better than what was designed by Sony, but you have to admit that the paint job and engineering needed to make this Sixaxis gun hack are pretty impressive.
