Get one of these 3 SDL screensavers:

On Windows, the screen saver uses QuickTime player. In case of problem, make sure to allow the player to read Adobe Flash file in the Advanced tab of the QuickTime preferences.

For Unix, download the swf file and use xscreensaver and the stand alone flash player. Macromedia's stand-alone Flash player has xscreensaver support, as of version 6.0.79 and later. To use it, put a line like this in the programs preference in your .xscreensaver file:

           "My Flash"   gflashplayer -root $HOME/swf/my_flash.swf
