since you are using the morph component in this definition, I simply scaled the geometries using their base points on the surface and there proximity to the attractor point. I'm not sure exactly what you are after, but I attached a new file ending in 3 which i think is what you want.
Thanks for the quick reply.
I have attached a pic with what i am after. With the only difference that i would like to have control over the tapering of each polygon curve. So, for example on one side of the wall i would like to have larger openings, and on the opposite smaller. (tapered)
thanks in advanced, if u have any tips would be good
