Speaking of a bright sun spot, consider the following setup:

hemispherical convex mirror mounted above a (hopefully
clear) ceiling window so that you can see, from
inside the room, the bright reflection

of the "dark room" photograph effect, I discovered I had the
camera obscura effect, but I didn't know what it was at first.
The difficulty came from the small size (only 3/16"

Thanks for a great idea,

Perhaps the work done for NASA to draw hour and date lines on images
from the Mars rovers' sundials could be used to reverse engineer photos
of earthbound dials.
Woody Sullivan posted some background info on the MarsDial a few weeks
ago (see below). One of the URLs he recommended
. If they are intrigued by it, the members might
want to commission a dial.
This request is not limited to tubes. Any clever idea is welcome.

The sundial can be reduced to a mark on the playground where a person has to

Hi Edley and all,
The plot thickens! What if, instead of a lens, a reflector is used?
Suppose I borrow the so-called Victorian gazing ball from my garden (a
large metal ball with a mirror finish, about 30 cm diameter) and mount
it at the edge of my roof. If I lie underneath it and observe
sundial?� (Without demolishing my neighbor's house or spending
a ton of money?)

A problem I have with email from individuals is that I don't recognize all the
sundial senders so I am likely to just delete them without reading, on the
assumption they are spam. However, if the subject is obviously related to
dialing, I'll look at it.
