Yahoo Pipes, An interactive feed aggregator and manipulator. Its GUI is almost the same with Apple’s Quartz Composer (you’ll need to have Xcode Tools installed).

Pipes is a powerful composition tool to aggregate, manipulate, and mashup content from around the web.

Like Unix pipes, simple commands can be combined together to create output that meets your needs:

• combine many feeds into one, then sort, filter and translate it.
• geocode your favorite feeds and browse the items on an interactive map.
• power widgets/badges on your web site.
• grab the output of any Pipes as RSS, JSON, KML, and other formats
