Now there's a bit of synchronicity. About an hour ago I finished my first draft of a script for this, after mulling it over for a month or so. Then I see your post.
Your first question: yes, I adore it.
Last question: don't know yet. It typically takes me two months to go from initial script, then practice, then rehearsals, finally to performance. But I've got a feeling this is going to play very well.
The main reason I'm writing this is because as I slaved over the script, several nuances occurred to me that I think will make the key move pass by effectively. It's the old Henning Nelms thing of: don't ponder misdirection, think about direction. The actions I've come up with are quite pleasing, those sorts of things that make one smile inwardly.
And, I've come up with a nice way to completely "soften" the mathematical/numerical feel. It is now a very decent experiment in telepathy with just a bit of a wry twist (which suits my style).
Again, this is still just "step one" and I won't be doing a run-through of the first script for another day or so. But I do believe the effect is going to turn into one powerful piece in my close-up repertoire.
I am most willing to share my blocking/scripting ideas with any legit owner of the item, should there be no ethical problems in doing so.
Anyway, I think it's a really decent method which simply needs a bit of thought given to the "silent" aspects of a performance to make it play.
Which is my long answer: I like it. Stop back in a couple months and I'll report how many cabbages and tomatoes were hurled my way. But my guess is that it's going to play well, and would be worth your time to investigate.
