The image attached shows the binomial distribution in the top row and
the geometric in the bottom row. The left column represents the
distributions without AA, but otherwise matching the previously posted
image for those two distributions.
In the right column showing the effects of AA - because it's interesting
to look at AA this way :-).
Normal (povr am2 random jitter) AA with the binomial in the upper right.
Povr's big jitter (well outside pixel, per pixel random sampling) with
the geometric distribution in the lower left. With this one there are
'harmonics' starting to show up as bumps between the usual discrete values.
