Ok, here's something a bit more interesting.
I'm attempting to research the capabilities of the human eye with respect to
 From what I can find is seems that the average human eye can see a maximum
separation of 1 arc minute per line pair to visualise point separation.
So, this suggests that an average cinema with a viewing angle of 30 degrees
from the best seat in the house (as seems to be the normal SMPTE spec) would
require 30x60/1=1800 pixels to match the maximum resolution of the human

Is this correct? Seems a bit too simple to me.
