help with tesselation//voronoi

Hi from Spain,

I'm totally new in Grasshopper and that's why I’m looking for some help desperately!!!!!

I'm trying to create a project similar to GROTTO from Aranda/Lasch architects. I have been playing around with a 3dvoronoi model and I have generated a few model rocks that I want to use to generate a kind of growth system but I'm sure that with Grasshopper this solid connection will be much easy.

I’m attaching a definition and a rhino file, the problem is that I’m just able to connect one rock at a time; I can’t connect them all together...

I attach an image of Aranda Lasch's work with Grotto.....this is basically what I’m looking for but I'm not able to!!!!!

Thanks for your help first of all and I hope someone’s knows how!!!Thanks, thanks, thanks....

 

Gracias a todos!!!!
