Fellow shadow Watchers, In my professional career, when, in an assessment capacity, I sometimes worked in close proximity to sculptors, industrial designers, graphic designers etc. (it shocked me when I met a graduate graphic designer who couldn't draw!! ... 'I'm not an Illustrator!" she said defensively, I would come across instances where the term 'sundial' had been hijacked to justify motive for a student project.
In one instance the 'gnomon' was an amorphous low-level dribble of bronze in the middle of a discarded windmill grindstone. "But it is a sundial!" said her tutor. "Look at these photographs showing the shadow at hourly intervals." "Mmmhh!!. Had you noticed that all the shadows are the same length? I asked." Now how could that be?.....by rotating the stone every few minutes perhaps?" Just an old cynic.
