Animated Concepts #3
A 0.85T 0.23
1Looking at the frames, I can see two salmon/coral colored dots near the center of a dark background. They appear to:
21. Start very small/invisible
32. Grow to full size (about 8px diameter)
43. Orbit around each other or move in a circular pattern
54. Fade out and repeat
6
7The dots appear to be rotating around a central point, with one dot slightly offset from the other (like two bodies in orbital motion). They pulse in size/opacity.
