Random comment:

The smaller parts should be circles not spheres if you want them to be the same size as the hole in the bigger part. If you make the smaller shape a sphere with the same diameter as the hole in the bigger shape they will go trough each other incorrectly. The sphere will miss the hole. The person who made this realized that and made the hole bigger than the sphere.

I've made that thing in 3d and it was upsetting when I realized that.

It's a really cool gif. I like how one is the Moon and the other the Sun.
