Display current state of a Jenkins instance using a blink(1) from ThingM (http://www.kickstarter.com/projects/thingm/blink1-the-usb-rgb-led).
Polls the server at 15 second intervals, and will display green if all jobs built successfully, yellow if one or more jobs are unstable, and red if one or more have failed. It will also blink if one or more jobs are currently building.
Simply run the python file, passing it the --host parameter to tell it where your Jenkins instance lives. You may also pass the --user and --password parameters if your Jenkins instance requires basic authentication. Jobs can be ignored by passing them as a comma-delimited string of names under the --ignore parameter.
Example execution for Windows machines (useful as part of a batch script)
python jenkins.py --host http://my.jenkins.server.com/ --ignore TestBuild1,BrokenBuild
