BigFoot is a Mac OS X "desktop critter" that provides you with endless entertainment, in the form of a pair of feet. But not just any feet! These peripatetic companions walk around your desktop, mostly minding their own business, but occasionally interacting with you in various ways. They dance, chase the mouse, play hopscotch, and lots of other things. Their appearance and behavior is extremely configurable; some appearance styles are shown here, and their configuration panel is shown below.
