Looks good Mike but my idea of old school is the hand drawn map in the photos, I like math though...

Murphy I am completely blown away that this thing existed in 1960. I wonder what else we don't know about...

Photos of old school method of looking at the lines. I am working on Sneezy so this one is gonna sit for a few days...
