YouMoGraph shows how to create one of those abstract-like animations in Cinema 4D using dynamics and some Xpresso to link spheres and lines together and have it all work so that it can be easily animated.

This type of animated style is really seen everywhere these days, however it is still quite popular simply for the reason that Cinema 4D really excels at making this type of animation accessible with the Mograph Module, Cloners, and Xpresso.

YouMoGraph has a youtube channel that he operates, that you should really check out.
