Educational GIFs

I'm slowly preparing a new post for the category "Physics for everyone". The post will describe the Lorentz transformation a bit more in depth, and say something about the consequences of it being the correct description of reality. I prepared two GIFs for this purpose:

A more detailed description of those GIFs will be a part of the new post in the category Physics for everyone :)

I published the code I used to generate them on GitHub:
