A bit of a different Happy Pic and about 15 years in the intending but 1 year in the making. It's an analemma, a trace of the sun's path through the sky over the course of a year. In this case, you make a mark of an immobile object's shadow once a week (you could do every day if you
really wanted to!) at the exact same time of day.
While you might expect the shadow to get longer as the days get shorter, the shadow also moves subtly to the left and the right because the Earth's orbit around the sun is not a perfect circle and thus moves faster when it's a little closer and slower when it's a little further away. So it falls a bit "behind" at the same time of day on those slower, further parts of it's orbit, and moves "ahead" at the same time of day on those faster, closer parts of it's orbit.
So the path over the course of a year makes a figure 8, and every figure 8 is unique depending on where you are on the planet and the time of day you make the mark. This is ours, but I haven't taken the proper perspective picture as I need to get up on a ladder to do so and I'm not feeling well today.
So you get a preview from a snake's eye level:

You can see the shadow edge we used as this was taken a minute or two after the final mark was made on Sat. The sharp-eyed will notice a missing mark from 3 weeks ago as the weekend was clouded out. We probably missed 4 or 5 days from this but have all the others.
