Yes my literary comprehension skills are quite lacking. I read it wrong
and realized this quickly after sending my post. Sorry for wasting
bandwidth, and wouldn't have done so again if it weren't for a little
comment on the responses.

We cannot resolve anything visually to atomic levels. The human eye is
sensitive down to about 15 photons resolution, and only in a really dark
atmosphere. Albiet this probably doesn't matter if the computer screen
analogy holds with larger than pixel objects at large distances which was
referred to in a different response.

I know a few particularly useless artists that I am currently setting to
work on verifying this with paint, and if there's any surprising results,
we'll get digital photos of it.
