Is this Khan Academy in disguise?? On a serious note I was kinda lost when I read just the algorithm online but this video just made everything so much clearer. Great job!

Could there be figures that do not change locations? For example, "A,B,C,D,E" could A ever be the first post-randomiztion?

[@fullmuppet]

Yes. But the same is true with a "real life" shuffle. If you shuffle a deck of cards, any cards could be in the same position after the shuffle. Indeed, to be a true random shuffle, this needs to be the case. If items were guaranteed *not* to be in the same position, that provides information about the previous state, which means it can't be truly random.
