Wonkavision:

System A has a page on which an image is displayed. The Querystring of the image contains a ?chunk= and the image is server off system B.

System B, upon receipt of a request to the "image" image, records the chunk and redirects to an innocuous image.

Once all of the sections of the image are located on System B...

System B displays an image from system A, passing the chunk back to system A

System A collects the chunks and reassembles the picture.

Just like the real Wonkavision, which chopped things and sent them to another machine, this will do just that. System A is the sending machine, system B is the "air" and system A (or system C if you had enough friends) is the receiving machine.

Come to think of it, this is like the "crazy machine" idea I had at Plural, where everyone built a page or tool which did a specific task, and they all chained together to make this endless loop of action.
