Here is an animation of the algorithm I proposed in advanced-users.

It is a water drop that has been excited with some crazy surface waves. 
  The basic point is that the damping and attraction terms in the model 
eliminate some of the computational problems associated with "stiff" 
long-range forces (like gravity with it's 1/r^2 attraction) and point 
particles.  The "binding force" is weakly attractive at large distances 
and weakly repulsive at short distances which is similar to how 
molecules attract each other.  The damping removes energy from the 
system and does not allow computational errors to be magnified into 
run-away particles that are "accumulating
velocities that exceed light :-P"

Anyway, the water is too lumpy. I think I have a much better algorithm 
for simulating liquids based on a mesh-like description, but I am not 
sure how easy it would be to implement.


I hope you are suitably underwhelmed. :)

P.S. I'll post the POV files in p.b.scene-files, though I think it's a 
pretty silly rule.  Already someone has to check three different threads 
to follow this little comment...
