Inspired from this: http://www.guildwiki.de/wiki/Glutstahl-Klinge I think that skins that are animated should be added to a (new) separate category as well, so people can browse through it and look esp. for items with an animation.
I'm not suggesting to add images showing the animation as the german guild wiki does (such pictures mostly have the filesize of a whole desktop screenshot and that's imo too much to load for an overview - even when it looks nice).
