Personally I'd recommend grabbing an old copy of qbasic with dosbox and going to town on some old tutorials here http://www.petesqbsite.com/sections/tutorials/graphics.shtml http://www.petesqbsite.com/sections/tutorials/graphics.shtml I know some would say it's a bad language, but back in the day it was incredibly accessible and spawned a lot of shared code and tutorials. If you focus on the techniques and algorithms, treat the language as pseudocode rather than "the right way to do things", you can have a lot of fun and learn quickly things you can translate to whatever your language of choice is.
