Here's a NSFW video about the Joydick, "a wearable haptic device for controlling video gameplay based on realtime male masturbation. Through the use of a carefully designed strap-on interface, the user’s penis is converted into a joystick capable of moving the character onscreen in all four cardinal directions. For games requiring the fire button, a separate ring can be worn which converts hand-strokes into button presses." (Thanks, Becky!)
