Hi Abbie, The following examples of interior sundials are from my own limited personal library and experiences.
Waugh has a chapter on ceiling dials in the classic book "Sundials: Their Theory and Construction" R1. Besides the design information, he tells the story of Newton designing a ceiling dial from his sick bed. In his book "Cadrans Solaires des Alpes" R2, Pierre Putelat includes on pages 04-41 a series of pictures of a ceiling dial in the Lycee Stendha in Grenoble, France. This was created in 1673 by a Jesuit Priest Jean Bonfa and restored in 1993 by M. Bouyer. It is now classified as a historic monument. There is a small (1 cm) hole in one of the window frames of the cloister at Canterbury Cathedral that casts a point off light onto at noon mark (Temps Midi)on the monks walk. Even while meditating, it is important to know when lunch is served. Woody Sullivan U of Washington is working with an architect in Seattle to use the path of a spot of light from a small circular window as an interior design feature. We saw it on the Seattle sundial tour at the NASS conference last September. The pattern climbing a staircase at noon on the equinox was spectacular. The field is wide open for innovative interior sun sculptures.
