Analemmatic sundials: How to build one and why they work
pdf more info / wikipedia entry / notes on kitsch
"After about eight months of trying to use [calculated] measurements, Mr.
duPont got disgusted and said we would build the sundial ourselves after
working out our own measurements. Both Roland Taylor and I [Knowles
R. Bowen] began the task of taking actual observations on the sun at 12
noon every day, after checking our time with the Naval Observatory at
Annapolis. If the sun was not out, we could not get that day’s sighting
until the following year, or maybe two years later, which explains why the
project took so long."
