Google unveils new look: Enters the world of subtle drop shadows
The old Google logo is about as the old as the internet, having gone through a few revisions it was still a little rough around their edges.
The new logo is a nice overdue improvement (in my opinion): just check out that nice subtle drop shadow, minimal bevelling and bright, web 2.0ish colors.
Also, If you try to save their logo on the search results page.. you will find that it is now part of a large sprite. Nice.
