I want to model bone structure with Grasshopper, how should I do it?

[hong]

I am an architecture student studying Grasshopper. I want to model a bone sphere using Bornoi as follows, but I am new to Grasshopper. Which algorithms should I use?

1. I hope that the thickness of the skeleton is not constant.

2. It should be able to create space inside, as in the following photo.
