So this is nothing big (quite ad-hoc made), but very often I meet either beginners or even mildly advanced Latinists who do not have a firm grasp on some distinctions as in+acc and ad+acc or ab+abl and ex+abl. So this should help them. It is really poorly done, since I made it quickly just for some friends...and there are so far only some prepositions, but the main thing is, that it conveys the idea I might add some later.
It covers only the basic motion (usually the other meanings are derived from it, unless in cases such as de+abl in about).
If you are a teacher, you can use it to facilitate your explanations
As the proverb says: One picture says more than thousands words -> One animation says more than million words
