When I've sorta-memorized something and want to better-memorize it, it helps if I can look at some letters and try to fill in the blanks. These word ladder memory drills help me do that.
Have a list of thingies you're trying to memorize and want to try turning them into a word ladder web page thingy? You can let me know or do it yourself.
