Relativity - Circle animation

This animation illustrates the desynchronization between the observer and moving objects considering the basis of Einstein's relativity.

The objects share the same animation - a circle pattern - which slows down as one moves backwards the camera and faster as one moves towards the camera.

This demonstration uses a very slow light speed (half a meter per second) to highlight the phenomenon.

I did the modelling and animation in Blender and I have done the scripting part to simulate the relativity as an add-on in python.
