Dave,
as far as I can see the smaller dials show italic and babylonian hours,
the latter at the right with the too short gnomon. The things sticking
out from the windowsills seem to be pipes to channel rainwater out and
away from the sundial.

about the climate there, but during
construction and hardening it has to be kept moist or the concrete will
develop cracks and will not harden properly.
I can supply links (and pics, if I go digging) if you are interested.

john,
when I painted a sundial on the wall of my house, I didnt get the lines
as straight as you did - and my wall is much smoother. very good work!
How long did it take?

layer is more weather resistant, or if proper
sealing is more important (which is what I would expect).

John (D),
you talk about pre-anodised sheets with photoresist applied. is this
anodising applied or removed by a photographic process? how does it
work? how do you make the color change?
sounds like a very intresting material for our purposes!

. You'd have to
produce a very tight layer of dots to show the shadow well. While the
newer machines can produce much finer dots (I think the piece in your
picture was made by an older model), they are still far from it.
why not sandblast the backside of a plate of glass?

with the sun back today I also tried the experiment with the
"CD-Gnomon". I also saw the false ellipse.
Could anyone -again- explain why the dot of light is not round? I didnt
quite understand it the first time ...
