It would be interesting to create a smoothly transitioning GIF of the principal B5 aliens who experienced changes in their appearance. G'Kar went from a more pointed facial structure to a softer, more rounded one, for example. Londo experienced a more polished look, but that can be explained by his ascension in Centauri power structures, bringing all of the money with it.
