Would someone please build FrooglePEG? Just a little app that hits froogle.google.com, selects from the front page list of "items recently found with Froogle" pulls one of the images returned, and displays them in a never-ending stream? Bonus points for making the speed at which images update configurable by the user.
Why? Why not! Who wouldn't want a real-time glimpse into the soul of ecommerce?
