I wanted to speed up using skritter a little bit when using pen and paper since grading was slow from having to hit show, then re-mark the character as correct, and then advance to the next character, etc... so i wrote a program to help out and then figured that somebody else might like it too. (its called skritteration)
Theres a better description inside the program, but, it's for writing prompt reviews only and it alternates between revealing the character (while keeping it correct) and advancing to the next prompt only using spacebar. (the only time any other key is required is if you write a character incorrectly).
anyways, thought i would just post it here incase someone found it useful
