Dasher
...and Prancer, and Vixon, and Nixon... wait. What?
Oh yeah: Splasm Software has released an update to Dasher, the cool little freeware app that lets you make Dashboard pop up on its own whenever you've been inactive for a user-defined amount of time. It's like a screen saver, except functional!
According to the FAQ, "Dasher is actually two pieces: a preference pane named Dasher and a background application named Dasher Daemon. The preference pane communicates your preferences with the background application. The background application keeps track of how long your Mac has been idle and activates Dashboard according to your preferences. Dasher Daemon is automatically added to your Login Items so that is active as soon as you log into your Mac OS X user account." Pretty cool.
I spotted this one via Dan Frakes' article on Mac Gems. Good spot, Dan!
