Wow, that’s really cool.

Where does it actually loop? It’s so seamless. Even with the colors and size changing. 

so, I used "keyframes" for the animation and so the key frame shows where everything is in that specific frame. So, to start, I made the symbol and positioned everything in the right spots and saved the keyframe for the first frame. I copied the keyframe from the first frame and put it on the frame exactly after the last frame. Then, to actually have dynamic animation, I went halfway through and changed everything to how I wanted it.

I don't know if you wanted the technical bits, but there it is. And thank you!

Also, you can see the loop when the circle starts expanding again, everything has a slight jump to it.

Storming heck man! That’s awesome! 
For a background you could do a starry sky or stars in the sky and stuff like that.

I love it!
