Would like to build a dashboard widget for Mac OS X to display wind data. My primary development environment besides Linux is Mac OS X. I haven't ever written a dashboard widget before so would like to learn how to do that and share the experience here.

The initial code includes a Flash rich internet client example for pulling feed data. Would be nice to add many more types of clients to the example list. I'm thinking of pure XHTML clients, Swing clients, Mac OS X dashboard widgets, PHP generated HTML, RSS feeds, etc.
