I am currently Program Director for our M.Sc. program in Economics and I therefore only teach one undergraduate econometrics course. I also give some lectures in Behavioral Economics in the Ph.D. program.
Inspired by Nick Huntington-Klein and others, I use animated GIFs as a pedagogical tool in my econometrics teaching. I have put some of the animated GIFs I have done below. The world is a better place the more people learn econometrics, so my animations are free to use for non-commercial purposes without attribution.
The individual frames in these graphs are generated using this Stata code and then compiled into an PNG animation using APNG Assembler which is then converted to a GIF using this program. This is not an ideal solution, so if you want to try yourself I recommend using the animation package in R.
