Round and round and round we go

I've spent a good deal of the evening setting up a new Macintosh desktop in my 'study' (cough) at home. The idea to try this picture (it's not an original idea, sadly) came quite late. It was surprisingly quick to do. I had to repeat the setup about 5 times before I got a nested set of pictures deep enough to lose the original Apple desktop. Apart from being a cool use of digital, it actually makes a surprisingly good desktop image to boot! BTW, my real desk is not normally that tidy.
