Skeletal Mesh Font - Voronoi > Weaverbird

Hi all,

I'm very much a beginner but hoping for some guidance.

I'm trying to create a 3D Font with a wireframe structure. Using the wireframe to then create a smooth organic structure. Currently doing this with "Pipe" (pictured below).

I'm trying to achieve a smooth structure like in http://www.grasshopper3d.com/forum/topics/skeletal-mesh 

I have tried the qhull method but I can't get it to work for me.

I think its weaverbird I have to use bu ta little lost...

Any tips would be greatly appreciated.
