Hmm . . . Maybe we should have called that thread, “My Back Pages” 
Might be worth mentioning quantization errors when considering the difference between a computer generated image and an analogue picture. [PS: Read the whole thread before I realised it was a Zombie, dammit.]
In this is it possible to have a particular picture never come up?
Or to put it in another way, if you have a infinite number of coins flipped, giving random heads/tails continuously, it is possible to have a coin that never flips heads?
Every coin will come up heads in finite time with probability one, but some of them might take a while.
Specifically, his tragic short story Funes the Memorious.
How about Mona Lisa in any Euclidean state, with, say, what it looks/looked like with any nth or mega-nth time before and after and combinations thereof?
Those monkeys are industrious buggers.
