What's the impromptu-ness factor? We talking minor setup a la angle zero, or full blown TNR gimmick goodness? Or is this something I could do with just a marker and a quarter and no clothes while stranded on an island with cannibals to persuade them not to eat me? Can the principle be applied to other effects? Is it tres tres difficile? What the reset (in other words, could I do it strolling)? Is there anything extra that comes with the DVD (gimmick, refills, etc.)? How are the angles (are there any)? I suppose that's all for now. I already ordered it, but I still am curious. Thanks, and this looks sick.
