Dan Garrett's routine is called "Epic Marked Down" and yes, there is some work in the markers, but they appear to be just everyday sharpies from the office supply, so there's no "magic prop" issues. The paper can be index cards, business cards, post-it notes, whatever.

-- I don't know if the routine is for sale but mention that I was bragging on it here and sparked your interest. I can't speak for Dan, but I know he's a generous guy. The routine wasn't included in the lecture notes but at the very least he might be willing to include it as an add-on if you purchase some of his notes or something.
