Alessandro Zomparelli describes a method for creating what he calls a 'dual mesh',
Alessandro writes:
Thanks to introduction of b-mesh it’s possible in blender, starting from a triangulated, to obtain a polygonal mesh in blender. This kind of polygonal mesh is called dual mesh.

I have a LONG history with Blender - I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-) I also run the Blender Artists forum and I'm Head of Community at Sketchfab.

That's a interesting technique.
Thank you for sharing Alessandro!
Neat exercise.
I tried the dual_mesh.py script on an icosphere and I get an error on line:
bpy.ops.mesh.dissolve(use_verts=False)
..or any mesh for that matter.
Changed that line to :
bpy.ops.mesh.dissolve_verts()
and it now faults at ...layers=(True, False, False, False, False, False, False, False, False, False, False, False, False, False, False, False, False, False, False, False))
Okay, deleted that line, changed lines where:
bpy.ops.mesh.dissolve(use_verts=False)
to:
bpy.ops.mesh.dissolve_verts()
Updated the graphicall code, should work now.
I got both errors as mentioned here already ( stuck at line 39 error with True False False False ...)
GraphicAll script does not work here:
OS X Build of Blender 2.68
Not sure if my edit overwrote his program or created a new code, but use this one:
http://www.pasteall.org/44242/python
Or this one (submitted as new code):
http://www.pasteall.org/44243/python
Yes, for some reason, the edited code keeps reverting back to original, so use only this link:

Nice idea! :)
Thanks FloridaJo for fixes!
Now it works perfectly ;-)

You're welcome, and Thank you!
That's the easiest way to make a graphene lattice I have ever seen.
Also the easiest way to create a golf ball from an icosphere.
Thanks for the tutorial! I didn't even know about dissolve, but have been looking for something with it's functionality since b-mesh was introduced.
With blender you can really learn something new everyday. Thanks again.
