Adding to my comment after a good night's sleep: To create a loop back to the first image is a bit tricky. You need to put in the zoomed-out previous image as before, but also a ring-shaped part of the zoomed-in first image. It's awkward to explain. One problem to wrap your head around is that the series of images you create by zooming out previous images has to played in reverse. I could imagine programming a shallow random-generated fractal generator creating series of images and then the infinite zoom would be really infinite, and this would be even easier than the loop.
