I am sitting here, upon the umpteenth viewing of the Kutiman video project called Thru-You.  If you have not seen it, you must, but I'll summarize it all the same. This man has created musical and video compositions mixed together from various videos gathered on YouTube.  To be clear, he's not mixing in video with existing music, he's creating music and video by editing the video, using samples to match the pitch and sound he's looking for.  He explains it here: What's particularly astounding here is not merely the quality of work he's produced, but also the raw material from which it was created. The very existence of this new work required such a vast amount of flotsam, which YouTube is all-too-willing to provide. Without the widely present "I must be broadcast so everyone can appreciate me" mentality, this project could likely not have existed.  It's recycling on an entirely different level.  I positively love it.
