The North American Sundial Society (NASS) is "interested in the study, development, history, and preservation of sundials and the art of dialing throughout the continent." Users can find applets that display the daily and annual paths of the sun and moon. The NASS message board allows sundial hobbyists the chance to correspond with each other. The website provides an extensive list of the sundials located throughout the United States. Anyone interested in the science and art of sundials will find interesting materials at this website.
