This might be the Mac-geekiest thing I've ever seen, but this is TUAW, so here you go. Sharp-eyed reader Morgan W has a flickr pool up of signs around the Apple campus in Cupertino, and notes that three of their newest building signs (at Bandley Five, Six, and Eight) have an updated logo with no 3D effect, and use Myriad for the font instead of Garamond, which the old signs used.
Will Apple's stock prices jump around at the news? Probably not. but as Morgan says, just like the missing Open Apple, it's another sign that we're moving further and further away from the "rainbow and serif Apple of yore."
