Variations of existing sleights are, if nothing else, a source of interest and stimulation to the serious student of magic. Evaluations of these moves is a challenge to these students, but thinking about what you are doing is, to me, the essence of good magic. A magazine, like Genii (or Precursor, M.O., Labyrinth or Channel One), is the perfect place for these variations to appear. I do get annoyed at books filled with this sort of thing.
As an aside, I passed up Earl Nelson's book, "Variations," because of the title. When I realized I wanted the book, years later, and couldn't find it, a friend helped me out by locating a copy. Thank you, Richard!
I don't care if Jon looks over his posts to correct minor typos or not. Having his participation here is invaluable and who cares about the spelling or syntax. Everything is clear (and, besides, that's what editors are for: ahem).
Let it flow, Jon!
