Maybe my imagination (it *is* late at night right now), but I think I see a
ghostly face in the top of the flames, just for an instant.Strange artifacts
though.

I wonder what the overall effect would be if you had two or three of these
flames side by side, but close enough to look as though they were part of
the same fire, each having different turbulence settings, and each
interacting. AFAIK, fires like the one in your animation don't have a single
flame 'source', instead having their flames distributed over a circular
area.

Just a thought. Good work.
