Voronoi Cells Shape


I am wondering if anyone could point me in the right direction for modelling a Voronoi cells structure. I basically have a solid shape that I would like to essentially fill with the form of these cells. Something like this but with a different shape: http://www.evolution-of-genius.de/3d/lawson_cube_voronoi_3d_2013_torolf_sauermann_math_art.jpg

Thank you,

That is exactly what I am looking to do. I have however achieved this through a different method that is very similar to the ones in this thread. What I am now looking to do is take it to a full 3D level. So instead of having just a mesh surface in voronoi to have a main mesh surface with a connecting mesh all the way through almost like doughy bread joining it all together to make it ‘solid’.
