Rhino and Grasshopper
throw some materials, lighting and dof on that!
Kyle, thanks for the suggestion, but I actually began by going the whole render route. I found that it’s such a complicated object that a raytrace with materials, etc., overshadowed (no pun intended) most of the structure and it was impossible to puzzle out. That’s why I went minimalist.
Looks great! Somehow reminds me of the Hellraiser movie. 
Thanks! I never saw the movie, though I was familiar with that pinhead guy.
