I'm interested in the ones you find the most informative! Especially those that can deal with not-sprites. (I'm not gonna be in 3D but I am gonna have vectors so it's like 3D but with 2 dimensions? is there a word for that? i should know that right?)
These are really for understanding calculations from 8- and 16-bit consoles so may not be what you're looking for but still might help you understand how to get certain feels down hopefully.
