Snackr is an RSS ticker that pulls random items from your feeds and scrolls them across your desktop.
Snackr can be docked to different sides of your monitor, or put on a secondary monitor so it doesn't overlap your other windows. Snackr is built using Adobe AIR and Flex.
About Adobe AIR:
Adobe AIR runtime allows Adobe AIR applications to be deployed on computers and devices running the Linux operating system. In addition, Adobe Flex Builder for Linux can be used to build rich internet applications that deploy to the desktop and run across operating systems using proven web technologies.
