My third class was Richard Salley's Solar Powered Timepiece and Compass Pendant.
I still have more to do on it, as the class went too fast for me to do careful work on the wire wrapping. The cover is an etched copper pendant - recognize my face? The dial is made of Faux Bone™ and the tooth at the bottom is one I bought in New York City at Maxilla and Mandible. The tooth is actually taking the place of a gnomon ("shadow caster") for the sundial.
Tomorrow I'll post my final piece: The Man in the Moon.
