Stuff like this is material for a background image on desktop. I use Bing Wallpaper of the Day for that (you can download the picture with 3rd party clients). This way, I always get the same background on every computer, but it changes every day, so whether I like it or not it is very temporary. Meanwhile, when my kids see it, it sometimes inspires them. For example, my left screen has all kind of fingers on it from Sunday afternoon when my son saw a labyrinth (its OK, I will clean it).<p>In AOSP / F-Droid there is Muzei which has a hook for astronomy pictures (NASA, specifically) [1]. Though it also has a Bing hook (it is modular). Smartphones have a different resolution so meh.<p>[1] <a href="https://github.com/kollerlukas/NasaMuzei">https://github.com/kollerlukas/NasaMuzei</a>
