I just had an idea for how to work the logo. The unfortunate thing is that I can't do it with WMM.
To start with, the Cata cinematic:
Scroll it ahead to approx the 2:20 mark, when the WoW logo comes on. As the words come on the screen, they shoot light out. With that in mind, follow me over here to our logo - or better yet, scroll up to the top of the screen. We see "GNOMEREGAN", then 2 off kilter gears, followed by "FOREVER".
So, here's my idea - Make a second logo with the teeth of the 2 gears meshed normally, just like you'd see irl.
A wave of light shining through the letters (similar to the video) starts at the "G" and moves it's way through the preceeding letters, until it gets to the gears. Then it stops. A gnome comes running in from the side with a hammer, and smacks the gears, turning them into our proper logo. The gnome turns and runs off screen, and the light comes back and continues through the "FOREVER".
As I said, I'm pretty sure I can't do this with WMM, but I think it'd be a neat thing to do.
