Another great American project, Fedspending.org is:

a free, searchable database of federal government spending…. With over $14 trillion in federal spending, this more open and accessible tool for citizens to find out where federal money goes and who gets it is long overdue. We believe this website is a good first step toward providing that access.

The project is run by OBM Watch, a “a nonprofit government watchdog organization located in Washington, DC. Our mission is to promote open government, accountability and citizen participation.” Funded by the very busy Sunlight Foundation.
