Some more random renders I found, still not happy with the quality and no time to improve stuff..

Beautiful. What exactly is "procedural glow"? I notice a glow-like effect, I assume that's it, but I don't know what "it" is.

Nothing fancy, I just apply an ad-hoc procedural function to determine how and how much every surface point should glow (really just setting the rgb tripplets to very bright).
For instance, in one of the scenes I tried to tweak it into looking like windows of a space city/ship.

The glow also acts as a light source since I have some indirect lighting going on (it's not very noticeable but you can notice a green tint on the "normal" mandelbox surface near the glowing parts).

The second-to-last one would be improved if the global fog effect was applied after the glow effect, so it dimmed and tinted the more distant "lights".
