I just spotted a new design for the "Ads by Google" signature below Adsense ads, it's an image, transparent around the edge (must be 24 bit PNG as it isn't too jagged), and it looks pretty cool! Is it new or have I been sleeping under a rock? It's the first time I see it. It isn't widespread on my site either, just this one page for the moment, the others still use the old text format. Oh, and I'm using Firefox (but what webmaster doesn't).
