NES Gamepad Mouse

Is there anything the humble NES controller cannot do? Somebody with a decent amount of technical know how and plenty of time decided to rip the classic NES controller apart and replacing its innards with parts from a mouse, bringing us the monstrosity known as the NES Gamepad Mouse. Granted, the nostalgic factor is strong with this DIY project, but when it comes to practicality, zero points will be awarded. It will only be a matter of time before your hand protests in pain due to the unergonomic form factor that welcomes RSI with open arms.
