A mashup
A YouTube hosted video commenting on the "special relationship" between Bush and Blair using "Endless Love" synced with publically available footage. Funny.

This was used (by Lawrence Lessig at the Linux World conference in Boston) as one of the examples of the new "participatory", "free culture" that started with hip-hop sampling and has now extended into the world of web-service "mashups" where people that were previously simple consumers now create by sampling and mixing whether they're dealing with text, music, video or software. All that new creativity and opportunity is under threat due to the malign influence of the recording industry, movie industry and Microsoft and Apple.
