It's cross-plattform and open source and free software. A good choice. > Can you send an image of what > you made? I do not know python, and my programming skills are rudimentary. I created with a friend our own gnomon, you see rendered pictures and a picture of the 3d-printed gnomon: http://picasaweb.google.at/finbref/Sonnenuhren I also calculated Martin Bernhardt's gnomon and uploaded an image to wikipedia: http://commons.wikimedia.org/wiki/Image:BernhardtscheWalzen.png If you are really interested let me know, perhaps I can help you with some coding to start.
