How to use JellyFish on hexa grid?

Hello

I am trying to vary a hexagrid on a surface using attractors

I found a JellyFish definition by Daniel Piker but I am not sure how to input just the curves so that they deform on the surface but without changing the surface itself...

Edit: I forgot to add that to create the hexa grid I am using a definition from LaN http://www.livearchitecture.net/archives/6174 and JellyFish definition I am experimenting with can be found on Daniel's blog http://spacesymmetrystructure.wordpress.com/2009/10/22/jellyfish-fo...
