Such Spinners, Much Loading
A 0.88T 0.24
1Looking at the frames, I can see a loading animation with a dark circle that has a white circular "hole" inside it. The white circle appears to rotate/orbit within the dark circle, creating a moon-like phase animation effect.

3The inner white circle moves from top-center position, to bottom-center, cycling through positions - essentially rotating around the center of the dark circle.
