With this plugin, you can monitor your Hudson server from the comfort of your Google Desktop.
This gadget uses the Hudson remote api calls, so should work against Hudson v1.92 and later.
Download the gadget package file from https://hudson.dev.java.net/servlets/ProjectDocumentList?folderID=9066&expandFolder=9066&folderID=2761
On a windows system, simply double-click the downloaded file to have it register itself with Google Desktop.
On the options pane, to change the Hudson URL, you have to select the existing url, then type the new URL. Otherwise, google desktop will think you are clicking the link and will launch a browser to the existing address.
Download the Google Desktop SDK, http://desktop.google.com/downloadsdksubmit
Under /api/tools, launch the designer_en application.
From the designer, open the project by pointing it at the google-desktop-gadget, "gadget.gmanifest" file.
