Oh, wait, now I remember -- for the second exam (and the last one before the Final Exam) of my Java class, I used a few create.swf images for it. Including an "animation" of Sakuya zipping around, and a sort of "duel with brooms" between Sakuya and Yumeko. (The winner was randomly selected, with a 50-50 chance of each, and Sakuya's victory screen had her in the Dio Brando arms-crossed pose.)
