I found that vimemu's graphical tutorial cheatsheets were a great, incremental way to get accustomed vim bindings. I can't speak to how accurate they are to the "real" vi/vim, but they've helped me get used to Sublime's vintage mode.

There are 7 "lessons". I just printed them out and stuck a new one in front of my keyboard every week or so.
