ScreenSave is a Javascript Screen Saver for Joomla! 1.5 (Uses Joomla’s native JS API).

It works just like any desktop image rotating screen saver. You specify a folder and it displays the images found there ( randomly on the screen ) after a specified time with a specified delay.
It also supports transparency and pre-loading.
Download: ScreenSave 0.2.0
Tested on Firefox 3 and Google Chrome. Made in scope of the Institut-Oko Kiosk project.
