Giant mobile foot!

This bizarre mobile foot is expertly piloted amongst the crowds at your event, to total astonishment and utter disbelief of onlookers. Why is it here? What is it for? Where has it come from? Either as a just-for-fun piece of street theatre, or as an act with a serious message (to promote sustainable transport or walking to work, for example) this act will always turn heads and provide photo opportunities.
