# This program decorates the screen with random images from the web.
# One satisfied customer described it as "a nonstop pop culture brainbath."
#
# software for any purpose. It is provided "as is" without express or
# implied warranty.
+
# To run this as a display mode with xscreensaver, add this to `programs':
#
# default-n: webcollage -root \n\
# default-n: webcollage -root -filter 'vidwhacker -stdin -stdout' \n\
+# If you have the "driftnet" program installed, webcollage can display a
+# collage of images sniffed off your local ethernet, instead of pulled out
+# of search engines: in that way, your screensaver can display the images
+# that your co-workers are downloading!
+#
+# Driftnet is available here: http://www.ex-parrot.com/~chris/driftnet/
+# Use it like so:
+#
+# default-n: webcollage -root -driftnet \n\
+#
+# Driftnet is the Unix implementation of the MacOS "EtherPEG" program.
