Roderick Valentin Hristov has a great program to make sundials out of upright glass cylinders. I have made several using graph paper inside the glass tube and etched the glass surface using my laser. They all look beautiful and the program is easy to use. He has invented a new program which converted a shepherds dial to a flat plate. I am amazed how simple it is and how well it works. Valentin is a great contact and extremely knowledgeable about his sundial variations. I recommend him very highly.
