I'm trying to recreate a povscene of Escher's Cubic space like
Frederich's Lohmueller at
http://www.f-lohmueller.de/pov/im_aa1.htm
http://www.f-lohmueller.de/pov/im_aa2.htm
the original lithograph is at
http://trese.cs.utwente.nl/taosad/SoftwareArchitecture/Images/EscherCubicSpace.jpg
Any comments or constructive criticism
I can't seem to do anything to make a similar bumpy texture for the bars and
boxes.
Also any ideas for the white higlight outside the bars and boxes? Right now I
just have a semi-transparent object only a raction of a unit bigger than the
object it surrounds?

Tree ways:
1 - use normals. Fast. Only affect the aspect of the surfaces, the edges will
still be straight.
2 - use mesh objects, one for the nodes and one for the rods. Rotate them
randomly. Fast and as you are reusing the mesh, you only use the memory for the
two of them plus some pointers.
3 - use some isosurfaces. Sit down as it will be sloooooooooow!

It would be faster to add the edge higlights with a paint program...

I would except, this will eventually be part of an animation (see attached).
It will eventually transition into a type of looping animation similar to that
at http://www.geocities.com/jeffwood581981/Lattice.wmv, which contains about
250 different frames (I think).

Ah, OK, there's a few things that would become obviously bad
in an animation.
Micro normals are bad, they'd flicker. You could still use a
patterned color map to make the beams look rough though.
I think post process edge effects would flicker too,
you probably are on the right track with putting some
media around the objects and then have it emit a little.
