Triangulate and Perforate

Hi,

I'm trying to create the surface in the attached image.  The goal is to triangulate the surface, and subtract the voids from the surface.  Eventually i'd like the subtractions to change scale (or fillet radius') based on their distance from an attractor.  Thus far i've followed the Surface Diagrid tutorial in Primer.  But have been stuck at that point.  Anyone know how to make this happen?  While i don't want to steal anyones work, screenshots of the grasshopper solution would be extremely helpful to learn from as i am still pretty new to this.

Thanks,

Damian
