Preface to this question is....I suck at this and am trying to understand, what and why, so any help here would be great.

I am looking at the pen trick in TM's Hide/Stealth script. I am trying to understand it but I don't really understand the step by steps of the trick and why that it works the way it does. If I could understand that the script would make more sense to me and I could work with it.

Thank you to any and all who can explain this to me.
