Neat process. Coming from Wings3D, I remember ggAliens having some plugin that could do geometry like this in a generated manner. Manifold labs stuff. :) On the Blender side, I wonder if the Sverchok plugin could make these kind of things based on a given set of a few input parameters? (Don't have any experience with it though.)

Other than that, I wonder if there's any plugins that would allow macros in Blender? Chaining a few commands even when manually modeling would likely make this go a lot faster.

I remember Manifold Lab.  I used it extensively when I first began modeling, because I was very much into the parametric and generative process of modeling complex forms, and ML was focused on creating a generative workflow.  GGAliens was doing some great work with Voronoi stuff in ML at the time.  I still peek in on his latest Youtube additions once in a while.  When I moved on from Wings, the procedures I learned in Manifold Lab really helped understand the mathematical, procedural processes that could be had with other packages, like the modifier stack in 3dsmax, or the powerful specials, and modeling combinations in Blender. The only macro recorder project I've heard of in Blender is this, which came out with Blender 2.6: http://wiki.blender.org/index.php/Extensions:2.6/Py/Scripts/Development/Macros_Recorder

This will record commands to a text block, and allow the recall of certain procedural object workflows.
