I'm gonna patent the use of a harmonica-type device instead, where instead of sounds, the harmonica-controller translates them to signals which can be set to be "button" on a controller.
I would also patent pissing into a urinal and a sensor to detect the stream's movement and flow rate to use as controls, but someone beat me to it; ****ing taking the piss is that!
