Japanese toilets are famous for their various functions, including touchless toilets and automatic perfume spraying, among others. Unexpectedly, Japan's SEGA Entertainment has taken it a step further by installing urine-controlled games on urinals in Tokyo men's toilets. One of these games determines the extent to which a virtual girl's skirt is lifted by a "digital north wind" on the screen based on the strength of the urine stream, leaving people in awe.
