Could you say more about this? If you examine an object more and more
closely you see more and more detail, and I understand that you have other
arguments suggesting that this is all due to the ensemble of computations
underpinning the physical reality, but are you suggesting that the fact that
you can observe these levels is *by itself* evidence for these levels and
sublevels of computation?
