You could also use absorbing/emitting media.

This is basically the same technique that I used to generate the ghostly
edge-glow effect in my last IRTC entry, 'Ghost Light' - still on the IRTC
homepage due to the hiatus. I can vouch for expanding a mesh along its
normals (actually I shrunk mine but it amounts to the same thing), it
worked a treat. I don't know about other modellers, but there's a suitable
tool in Blender that does this.

Nice demo, by the way.
