I think the black is from over lapping container objects.  I used a few
of them to try and make the smoke.  You can't tell from this angle but
the smoke is flowing away with the blood flow.  I tried to make some

about that.  I couldn't decide on how to make it look like a thick
fluid.  My attemps at media did not turn out.  Thanks though.
