I haven't looked at the video in a couple of years, since I quit
full-time teaching. I don't have it with me--it's at school, but I'll
try to take another look at it in the next week or so and see if I
can answer your comment. When I saw it done the first time, I don't
recall having any problems following his development.

Maybe I shouldn't admit to that :-)
