>Or, instead of using a person, I could place a vandal-resistant vertical
post, pilar or obelisk at the dial center which could be used for sunset &
sunrise date/time/ direction readings and this would also give the dial a
three- dimensional aspect as suggested by Sara Schechner. This would draw
attention to the dial.  Also, the hour lines would radiate from this
point.<

You will need to form a balance between having the pole as an attention
drawing device and it generating its own possibly confusing shadow. 
Incidentally, if you had such a pole you could place a nodus on it and that
could be used for declination lines....

the
summer and to accomodate short people, it will be very important to mark
the
hour lines as close as possible to the gnomon foot (where the people
stand).
Correct?<

Yes it will - but that is good because the presence of hour lines helps you
with very short shadows.  A true analemmatic dial has no hour lines and it
is this that makes it hard to read at all accurately with humans of short
stature..

>By the way, what do you think of marking the places the human gnomons
should
stand using four sets of  footprints (4ft. 5ft. 6ft. & 7ft,)? Sort of
corney
and not very artistic, huh?<

No not at all.  In fact I would encourage you to do it because in my
experience people using human marker dials tend to put their toes up
against the line rather than the underside of their heel (which is more
likely to be directly under your head!).  Footprints would therefore help
eliminate that error.  Of course you need to place the heel of the drawn
footprint in line with where you think their head will be!

All the best
