Screaming Penguin - Source Does Matter

Ok, here is a new toy for everyone.
Available for:
Win 32
and
Unix(You can use the Unix version on Mac OSX with some caveats. See jwz's site for details ).

This will read your account on the new aggregator system (enter your user and pass in the screensaver prefs screen) and display the contents of your feeds. Woot!

It will also create a .totspscreensaver folder in your home directory. You can drop any number of standard format images in there and it will use your images as the background, rather than the default.

Be advised, you need a 1.5 JRE installed and on Windows it HAS to be your Windows-registered Java. See HKEY_LOCALMACHINE/Software/Javasoft/Java Runtime Environment/Current Version if you are getting segfaults.
