The Vinegar extension for Safari is pretty good.

Check out John Matthias & Jay Auborn’s album Ghost Notes it’s really great.

If you like Memmy id recommend giving Bean a go too.

Another vote for The Weekly Planet here! Great Aussie banter if you like your comic book movies and tv shows or just current movie reviews.

For the physical version the only thing I’d recommend is making sure all your pieces of paper are the same size. Thinner paper (100gsm or less) will be easier to flip but the thinner you go the worse the drawing surface.

Digital-wise you could give https://flipanim.com/ a go. It’s pretty easy to use and emulates the physical construction of a hand made flip book nicely.
