Attractor Along Wood Slats

Hi,

I am working on this interesting project, where I want to manipulate a 'Strand' of wood slats (6" x 2") on edge using attractors.

There are two kind of manipulations I want to do:

Manipulation 1: Spread wood slats along base surface

Manipulation 2: Bulge wood slats along base surface

The idea is to try an maintain the structural integrity of the wood slats. The base spacing between the wood slats is 6" on center. And the length without deformation is 330'.

During both type of manipulations, the wood slats should not intersect, but the spacing can get tighter. The closest they can go is butting one another. The edges have to be maintained.

I know how to do this in Rhino using 'squish', doing the manipulations in plan / xy-plane and then 'squish back' or use 'flow along surface'. But I am looking for a more dynamic way to manipulate it 3d using attractors.

See attached images. I started with Danny's 'Stripe model attractors' definition, but do not know how to translate this onto the 3d surface / 3d lines / wood slats. Any help with this would be amazing.

I have attached the base rhino file along with Danny's definition. Thanks in Advance.
