This is a video of a Syrian sufi dancing ensemble. When I followed the Grateful Dead around we had a kindred phenomenon for a while. Guys and gals dressed in tie dyed dresses would ply similar moves in their psychedelic fury. They were known colloquially as "spinners". You would have to amble through large packs of them in the lobby in order to get a drink.
And no, I never took the leap. Or spin.
