Not sure exactly what a gender-swap workshop is-- are you sure that's a topic
for a dance e-mail list? ;-)
I've had fun at a workshop with skilled dancers teaching a reasonably normal
dance (e.g., not one with a lot of idiosyncratic moves), running it half a dozen
times so everyone learned the sequence, stopping the music, telling folks to
change sides and dance the opposite gender role, not giving them time to think
much about it, and then starting up the music again.
In the middle of some brain-busting dances, it was a pleasant and fun change of
pace.
