Script to replace Google logo with Evil Google logo

Amos sez, "Your coverage of Evil Google has inspired me to write my first piece of Javascript. It is a greasemonkey script for Firefox which, when installed by a willing user, will swap the Google logo with the Students for a Free Tibet version. Tested on google.ca, google.com, and google.co.uk. If you swap a line in the script, it will work on google.cn instead. I'm not clever enough to have it work for both at the same time."
