I'd like to use an SWF file as screensaver.
From xscreensaver FAQ:
To play SWF Flash animations:
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/movies/my_flash.swf \n\
Every version of the standalone flashplayer I found has no
-root option and I can't find gflashplayer.
gnash -x $XSCREENSAVER_WINDOW doesn't seem to work.
