Thanks!  Can I set up the conditions such that a smoke ring should be blown? 
Sure.  No problem.  Can I actually get a smoke ring out of it?  Hmmm... 
Doubtful, but I'll try it sooner or later.  Take no offense on the later;
I'm just busy.  Plenty of time to set something up and let 'er fly, but not
enough time at the moment to fine-tune something like a smoke ring.  On
that note, and on a bit of a tangent, I just think it's kind of ironic that
I didn't really do my differential equations homework or study for the test
because I was too busy... solving differential equations.  Oh well.  I
suppose there's no time like the present to do some real studying.  Oh, and
once I get it put together a little more, I'll post the code so you'll be
able to give it shot too.
