I made a "widget" for Mac OS X 10.4's "dashboard". It pulls down slashdot headlines via RSS every half hour and displays them in a nice window.

Interestingly, Univers Mac ("MacWorld's French equivalent", according to the email) will be including SlashBot in their next issue's CD-ROM. Google reveals that I received a boilerplate email from "Pierre Fontaine" asking for permission, but hey. French people will be using my widget. :)

Widgets are pretty easy to make. And the tools and SDK are free!
