I had just come in here to comment on how much I liked the new Zeitgeist logo and slogan. It looks great, has interesting motion, and tells a ton about the campaign (I'm assuming PCs will build or fight mechanical monstrosities which trying to effect positive change by influencing the masses in some way).
Not allowed to give you more XP right now, Klaus, but it's an awesome logo! Between the logo, factoids, and the campaign world overview, I'm excited about this campaign.
I dig Girl Genius too, but ZEITGEIST will have a very different tone, and possesses a lot more elements of classic fantasy, rather than being wholly steampunk. But I've said too much already.
