It looks to me that this widget would be useful for the next MacWorld Expo to help us get around the Bay area.
The Bart Widget is a trip planner for the BART train system in the northern California bay area.
Instructions for use are simple:
1. Open dashboard.
2. See when the next train is coming.
3. Enjoy your smog-free public transportation.
Advanced use:
* Drag baubles on a map to set your route.
* Click the clock to set the date and time. (You can also drag the display or mousewheel.)
* Click the heart to bookmark your route.
* Click the speaker for voice announcements.
No network connection is required. The BART widget is a self-contained trip planner that you can take with you. It’s free and open-source.

I love it!
