They were just shopped photos posted on the windower forums (and again on KI forums) for an example of what someone wanted the windower Devs to try and do.
Alas thats beyond the realms of just straight UI editing, thats more like breaking the game down physically and re coding it to look in a certain way and to add extra features which have previously been unavailable. It's way too much of a job for most of the Windower Devs.
Atleast for the moment. They haven't even fixed windower macro bugs, doubting this is gonna roll on the scene any time soon.
