Now this is awesome and share-worthy to the extreme: a UI built around incorporating 3D spell effects from WoW into the UI elements that support them. Using a combination of WeakAuras, ingenuity, and lots of beer, Kait:Auras was born. Is it impractical? Yes. Is it awesome? Double yes. If you're going for eye candy, pack it with sugar and calories.
Just when you think you've seen the last out of the World of Warcraft UI, someone comes along and breaks the game with a poison swapper or allows you to draw a phallus army all over Dalaran. That sense of adventure, that the whole game could come crashing down at any point because of some enterprising young upstart, was what fueled the fun of the addon community and development -- the off-chance that your addon, in the grand history of addons, would change the world. Making the game better was one thing, but the unintended and often hilarious consequences of giving Blizzard such a (relatively weak) headache is kind of fun.
