Many many years ago when I was playing with AutoCAD I made an image that had an remarkably large level of zooms in it. You could zoom in on the picture and find even more pictures, then zoom in on that and there were more, an unending series of images that were small only relative to where they were referenced from.
Someone has to put together the ZoomQuilt, a Flash animation that lends far more artistry to this comment than I ever could...
