This takes me back. I wrote something like this a few years back, but ended up hacking the heck out of it to try to make it remember starting positions, and then giving up and using Flash. In your version, the more vertical the line is, the faster the box moves; also, lots of clicking eventually seems to break it. And a purely vertical click to the bottom left corner does nothing at all; which makes sense, because the original algorithm has to have x!=0, otherwise it's dividing by 0. The increasing/decreasing speed behavior based on slope is fascinating. There has to be some kind of use for that. Cool! This takes me back.
