Thank you for downloading this software!

BackLight provides a menu extra (really an NSStatusItem, which are fully supported in Jaguar) that allows you to turn your screensaver on and off as your desktop background. It's quite a cool effect really, but you should probably have a Quartz Extreme-capable machine if you want to handle the load.

Requires: 
Mac OS 10.2
Quartz Extreme highly recommended

Documentation:
BackLight adds a menu to the system menu bar to access if features.

Simply choose the "Start Screen Effects" menu item to start it.  Then choose "Stop Screen Effects"  to stop it.  

To change which module is running, open the screen effects preference pane and select a new one.  Unfortunately, at this time you will have to stop and then restart the screen effect to get the change to take place.
