Thanks to all of you who sent me pics of the Schmoyer sundial. I recognized it when I saw it, and it is a very interesting piece.
I will add the pics to my little electronic archive of sundial images. I am always excited to see sundial pics, so thanks go to Francois as well. I used to live and work in downtown Chicago, and it was nice to see the skyline again as well as the sundial by the planetarium. Jim Tallman, FX Studios.
