I had asked a question earlier about how to design a contraption such that a sunlight beam falls on a place (or point) exactly each year at a specific time. Having gone through the responses and realizing that I will have to learn to do some basic solar position calculations myself, I have implemented it and made it available through a web site - please check it out and let me know if it is right/wrong/ or simply works. Thanks!
