A twelve second loop with no visible seam. Works with the live-wallpaper apps on Android, and with any app that turns a video into a Live Photo on iPhone.
The North Star set into the compass mark, on a sounding field. Two motions built from the same drawing: a beam that turns and finds things, or waves leaving the mark and fading. Both loop seamlessly, both are free, and neither asks for anything.

One frame at full phone resolution. This is what most people will want: set it as a lock screen and it is done.
1290 by 2796 for recent iPhones, 1080 by 2340 for most Android phones. Either will scale to a screen it was not cut for.
Five fronts leave the mark, expand, and fade. Nothing rotates, so it never pulls your eye to one side of the screen. The quieter of the two, and the better one to look at all day.
A beam turns once every twelve seconds, dragging a trail that lights the range rings as it crosses them. Seven contacts sit at fixed bearings and glow when the beam finds them.
