  1. First time I saw this I HATED my teachers for not introducing this to us. Ok… feeling is still there. BASTARDS! I’m sure they knew. BAAASTAAAAARDS! Omf, so much time wasted with rulers.

  2. I don’t get it at all, and I do this sort of thing for a living. Demonstrates? Demonstrates what? You can move string to five places on the paper and fill stuff in away from the ray (line) at a different angle? Perhaps I am just expecting more from the demonstration (like information). It’s looks cool, but that’s all I am seeing. I’m a little slow sometimes. Perhaps my expectations are too high, or I am just not catching on. Or, perhaps it’s just a cool looking giffy thing everyone wants to one plus so they can look cool too. I don’t know… I think that’s the issue… I looked at the article, and feel like I should come away with a little education of what I just looked at… I want a refund.
