Hmm, maybe if you increased the component's radius, it would look more 
"fluid".
This animation demonstrates one of the problems with my patch: the 
liquid's volume isn't conserved. Inter-particle forces can help to fix 
this, but they still need work.

The only thing I can think of: did you use wind? It looks like you have 
a strong, slightly upward force pulling the particles along the wall.
What do you mean by variable elasticity?

Chris thinks...
Did you decrease the elasticity in the system for each successive frame? 
That might make this effect...at first, particles would bounce away from 
the wall. Then, as the amount of energy they loose increases, they would 
bounce closer to the wall, and eventually would lose enough energy to 
slow their fall. If there is wind or gravity pushing them against the 
wall, they would slowly "drip" down it.
