I found there is a similar question here. Forgive me since I don't quite like the answer given there—the font, the format, etc.
What I want is something like the one given here. I think it's of the same kind as Michael Hopkins's (one can search YouTube to see Michael Hopkins's slides).
I'm very grateful if anyone can tell how to make that kind of slides, or better, give a template for the slides as an answer. I even don't know if it is made by LaTeX; so if it is produced by some other thing, please tell me what it is, then I can learn how to use it.
(I also want to know how to make the beautiful pictures like the sphere, torus, higher genus surfaces etc. with various colours and submanifolds etc.)
