There was an excellent example of wireframe texture technique (fairly certain it was in code archives too) - this would be a good idea to get those 'tron-like' effects, as you can blur/fade-out the lines to give a more light-like appearance.

Whilst thinking about it, would it be too slow to render twice with wireframe camera and a normal camera?
