If you were a user of Greasemonkey, the add on for Mozilla Firefox that allowed a user to run custom javascript to alter certain or all websites that they viewed, then you'll love Greasemetal, its port for the Google Chrome browser.

It doesn't currently work with all scripts, but most of the popular scripts on UserScripts.org work. (doesn't work with the nofollow highlighter)

Run Google Chrome with the extended capabilities Greasemetal provides by launching it through the Greasemetal shortcut now in your start menu.

Many kudos the guys over at 31 Tools / Cybozu Labs for porting this over!

Installing Custom Google Chrome Greasemetal Scripts:

Download .js files from userscripts.org and place them in the userjs folder that was placed in your My Documents when Greasemetal was installed.
