I don't know...I don't think "normal" people should be able to read those things.  All I remember from his speech was the topic and the line thicknesses mean different things.  I had that class back when I was in 10th grade which would put that at about 7-8 yrs ago.  That's a long time to try to remember something that I don't have an interest in!
