If you've visited Google today, you've probably seen the special logo that Jim Lee designed. Here is a slightly larger version of that, taken from Jim Lee's Deviant Art page.
I think it's a really cool drawing. You have to love Plastic Man making up two of the letters like that. Superman isn't here, but that is all right--I like seeing Plas and Green Lantern getting some love.
You can also see the pencils for the Jim Lee's Google logo on CBR Live. In addition to all of this, you can select a number of comics themes for iGoogle, including Jim Lee's Wildstorm line. Nuff said.
