| POPUP SHADOWS |
This file is helpful when reading Illustrating Shadows because it allows a dial to be rapidly made and then manipulated to see how orientation
affects the shadows. This file, while built for latitude 32, shows how to move the equinox line, the dial center, and thus the hour lines. This is
more for interest than a serious dial, however it is most instructive, and adds a new facet to gnomonics.
The spreadsheet reference-spreadsheets.xls has as its first sheet a simple method of determining hour line angles for any latitude.
These dials are discussed in ILLUSTRATING SHADOWS for a detailed table of contents or here for a chapter index.
This file is about 150K. As with most files here, this is in Acrobat PDF format, and if you do not have the acrobat reader, it can be downloaded
free. There is a link on the main web page.
You may consider the FREE MICRO SHADOWS, or SIMPLE SHADOWS which talks only of horizontal sundials, in a do-it-first-then-fix-it-next
step by step process, as well as discussing what happens and why it works and then stepping you through the process. Tables are provided.
Simple Shadows is a free sample of the book 1.

This is a PDF file that has a
horizontal dial designed for
latitude 32, a useful latitude.
What makes it different is that
it is a paper cutout and
popup dial!
Also, this file has a pop up
dual dial, with both a
horizontal and a vertical dial.
Both are included in
CUTTING SHADOWS.
