Any computer with Java installed can also run the validator from the terminal/console as a commandline tool. Download the css-validator.jar jar archive (or build it with ant jar) and run it as :

java -jar css-validator.jar http://www.w3.org/

Note : the css-validator.jar file must be located at the exact same level as the lib/ folder to work properly.

Update: To get it to work, I checked out the full distribution from CVS and ran ant using the included build.xml. It downloaded all dependencies except for servlet.jar.
