Mutant Darwins
If you are looking for a reason to retire your current login icon, please consider adopting one of the Darwin images below...just shrink it to fit your needs, or GIFize it if you need some transparency. Or modify the image to satisfy your own higher standards for image quality -- I won't be hurt! Sure it's a bit lame, but using one of these images can really help promote awareness of evolution, which isn't so lame, and will almost certainly deter those frisky, anti-science zealots from hitting on you through the ether.
