I didn't like the word, "nice" much till I learned where it came from - niche - which means notch. Something was "nice" when it was a perfect fit. It is a much more clear and powerful word than oft used. Well, Analemma is a nice program, a perfect fit, for understanding in a much deeper way how our planet (and others) moves around the sun. It is clear, tells you what you need to know and not what you don't need to know! Nice! It has splendid graphics that are not over done. They are crisp and clear, just what is needed to get the concept. The author(s) exaggerate! The show a few more degrees to help demonstrate the concepts. Again, perfectly suited to get the gist of it all. While it is comprehensive it is also short and to the point, with easy navigation. It does it's job, used movies well and even has a calculator. I am interested in the stars and planets, in physics and in practical applications. I will be returning to this app over and over just to enjoy getting the concepts really in my mind as I explore what it means in my daily life. We live in Alaska so the sun is never "as it should be" but wow! It is so much more!
So, high kudos to the author(s) for their job well done. And a tip of the hat to Galileo Galilei! Nice! (The church in Pisa moved in analemma I believe!)
