[2.1] Gnome: just copy the files from extracted "Flurry" directory in /usr/. I wrote a little script to make it easier.
##########################################################
#!/bin/bash tar_file="Flurry.tar" #extract rm -rf Flurry tar xvf "$tar_file" #copy files cp -u -v Flurry/usr/lib/xscreensaver/flurry /usr/lib/xscreensaver/ cp -u -v Flurry/usr/share/xscreensaver/config/flurry.xml /usr/share/xscreensaver/config/ cp -u -v Flurry/usr/share/applications/screensavers/flurry.desktop /usr/share/applications/screensavers/
##########################################################[2.2] KDE: copy the files in /usr/ and create "/usr/share/applnk/System/ScreenSavers/flurry.desktop" with the following content. It will put flurry in the KDE screensaver configuration menu and let you set the options:
