Tutorial Video on Piezoelectric microphones for posterity

Today I finished making a tutorial video about contact microphone construction.  Besides the explanation of how to make a microphone, I tried to convey the idea that once you capture signal, you are only limited by your imagination in how you use it.

I made a little electronic-improvisation in Ableton using a few loops and a number of audio effects on our video clip.  First, I matched the sound, as captured by the Sony recorder in the video, to the video from the point-and-shoot.  I then loaded the clip into Ableton and did a brief sketch with four samples of the video.
