Players interact with Toylet by urinating on a sensor placed inside the urinal that measures volume and pressure. That input controls the videogame, shown on a screen mounted at eye level. The games include filling coffee cans, squirting milk out of a tough guy’s nose and blowing wind up a girl’s skirt. Each game lasts less than a minute and can be followed by a advertisement placed by the operator.

Brilliant, or incredibly creepy? Japan, you never cease to amaze.
