Here is a sneak peak at my upcoming short animation project aimed at making a course. Will post the final 2 minute short once done by next weekend or so, hard to say being a full time dad! 
Psst, right click loop
Here is the one on youtube with title.
So far there is 22 hrs recorded on this project which will be composited into a course. Some repetitive parts speed up and some others slowed to further explain certain things. Also will use annotations and visual cues here and there. The course will be done I have no idea when, but I’ll sell it on Blender Market for cheap once done too 
Peace!
