Ummmm... okay, so I just went and read the PDF and... I HAVE READ THAT PDF BEFORE. Like... at least the first part. I was just sitting there, going, "Fireflies? Needles? Light sensitivity? THIS SOUNDS CURIOUSLY FAMILIAR." It was crazy, especially since I have no idea why I read it before, or where I found it.

Anyway, read through it again, definitely think it's worth checking out the rest of it, and will order it as soon as I get home. (I can't order it while I'm here, because already I have way too much stuff for my suitcase going back, and I need to conserve weight any way I can.)
