CSS logo

I was making a draft of our new web site (why me - I don't know, no one else got around to it)
Anyway I put the WAI AAA logo on it, completely by CSS - I.E. no text in images.
If we want to use it as an alternative for the non component logo, then feel free. (see globalformats.com I know I have to fix it up a bit - just look at the logo)

Should we do the same to the other logos on the WAI?
