I found an app on Git Hub called WallPapper (Notice the two P's). It worked, but not well, I had to create a JSON document that would tell the app how to create the picture.This app is 1,000x easier. I can create any dynamic desktop without an issue, and I don't have to pay anything to do so.The buttons were a bit confusing at first, because they are icons and not words, and I didn't really know what the icons meant, but after playing around with it, I got the hang of it quite easily.The results are amazing, and it makes working on my Mac a lot easier. Thank you for this! I love it!

Look no further because this app is exactly what you are searching for. Free, clean design and super straightforward to use. If i was going to offer any notes for future releases, I would say perhaps there could be a way to set the solar calculations without needing to copy paste the values from one window to the other. Either just a one click button to set them to the currently selected image, or perhaps a gui where you can place markers for each of the images onto the solar chart.

My only regret is that I didn't find this sooner. This app was able to help me add all the data I needed even though I still don't really understand what the strings of numbers mean. It also created everything as the exact file you need and even shows you how to make sure it's set properly. This is simply wonderful.

Great simple app. Well put together and very effective for what it was built to do! If you want to creating something a little more interesting for your desktop backgrounds, look no further, it's all here.
