Anywhere from Nintendo 64′s rumble pack to your cell phone (pleasure mode, anyone?), electronic devices with a vibrating feature are subject to dirty jokes. Mojowijo have made our fantasies a reality.
The functionality is quite simple. The movement of one controller causes vibration to the opposing controller.
It is great because you get the vibrating sensation, but it still involves your partners touch, in a sense. There is still mystery involved because you are not in complete control of what you are feeling. It is also revolutionary for long distance relationships!
Way to go, mojo.
