"Dear Francois, Thanks for producing such a fantastic and easy to use program. I have already told one of my friends about it and we intend to make a couple of sundials for our back yards. I have access to a CNC milling machine so I can't wait to produce the hour plate. I'll send you a picture when they are done. So much information on your web site that really interests me. Great job!"
