On this topic, what's a good way to grow the particles "organically".
For example, have particles grow or change outwardly from a point of
origin? Similar to how a moss or other growth would encompass an object.

not really :)
so this move to closest location now worked as expected then or
not? if the 'hand' or surface is moving or deforming you could
also account for a velocity force from the closest location as
well. point position is not the only thing you can get from a
location.

This actually gives an undesired result, basically the
particles kind of stay inert not really following the surface
(that is deforming/moving underneath) imagine u have a ball on
your hand and move it quickly, the ball inertia makes it stay
where it is then it drops/sticks to the closest surface (could
be your other hand or the floor)
:)
What i really want is for them to move on the skin surface,
lets say from the tip of your index finger to the base of the
finger, while your hand is moving...
Hope this makes my point a bit clearer :)

If you use the get closest location - then the position it
returns you can feed right into a self.PointPosition set
data node - if you type into the search box 'set point
position' then you should find a node. If you put that
setup after any other forces or move nodes, then it will
make the movements then stick the points to the surface.

Sorry, Rob, not really sure what you mean with "set
closest location"

also a get closest location (your surface) > set

will stick your particles to the surface but still
allow them to move
around with forces and simulation.
