EARNING YOUR TV TIME….Via Ann Althouse, here’s a fascinating free market solution to the problem of child obesity: a new kind of shoe.

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.

It calculates the time earned and once it runs out, the TV automatically switches itself off.

Of course, this isn’t quite a free market solution yet, since no one actually sells Square-eyes yet. But give ’em credit for ingenuity just the same.
