Pillow structure

Hi I was wondering if anyone could help me,I'm pretty new to grasshopper. 

I basically want to create a pillow structure in the shape of hexagons, I then want to apply this pillow structure to a dome surface in a uniform way . 

The image below is one of Buckminster Fuller's drawings, it's a pneumatic structure, with several layers of inflated pillows. It's what i'm trying to achieve by the end. The layers alternate between dodecahedron and hexagon pillows.

any help would be much appreciated
