You might ask...
How does this site make money?
It doesn't and the YouTube channel is not monetized either. I teach Animation Physics at San Jose State University and put all of my course materials on-line for free.
Have you worked in the animation industry?
Yes, see my IMDB page.
Would you look at my reel?
Sure, I can give you feedback regarding the physics in your animated work. Contact me at my university email (Alejandro.Garcia@sjsu.edu)
