Sundial

A real horizontal sundial, not a decorative approximation — pick a size and a latitude band, and the gnomon's own angle and every hour line are computed from the real physics for that location. Add a message if you like.

Sets the real angle of the gnomon (the shadow-casting blade) and the spacing of every hour line — a real horizontal sundial isn't evenly marked.

Letters, numbers, spaces, and basic punctuation only. Engraved into the clear center of the dial.
