I suggested a blindfold class a while back, but now I'm not so sure. It's great to avoid anticipation, of course, but lots of moves have a visual lead, and lots of leads have a visual component to them; hand signals, nodding meaningfully, staring in a deranged way (OK, that last one's probably just me).
I'm not sure about the beginner's move set, but are things like the catapult included? Hmm, I guess it is leadable without visual cues...
It's an interesting idea, but in the average class (esp. beginner class) it could lead to chaos (people bumping into each other etc). And in an intermediate class you'd have to tailor the moves carefully to pick non-visual cue moves - not impossible I guess, but you could still bump into people...

I think this is a great idea, but it's best left to style workshops, where you have time and space to focus on this sort of thing.
