Awe-inspiring. Truly amazing.
Can you blow a smoke ring with that sucker? (i.e. a sort burst of steam
through a round hole in the front of a drum) It looks as though it has
enough complexity to develop and sustain a vortex ring, there are the
beginnings of one in the posted animation, but I'd love to see if you could
make one with an existing system (w/o adding support for it, I mean).
