Via the BBC, a shoe that controls the amount of TV Kids watch:
The shoe - dubbed Square-eyes - has a unique insole that records the amount of exercise a child does and converts it into television watching time. One button on the shoe - the brainchild of a student at west London's Brunel University - records the amount of steps taken by the child over the day. Another transmits this information to a base station connected to the TV.
Here are both the base station that converts steps to TV time and the shoe's insole: It seems that there are more and more shoe/foot/toe based interactions lately!
