Small wind-up toy being wound up and allowed to walk by the mic. The wind-up key is then abused a bit, making a sound not entirely unlike a scratching record (but not much like one, either).
Stereo recording of wind. Recorded on an electret microphone on hi-md. Has been processed. I took a section of wind that represented a heart-pulse since its a vital element to carry oxygen. The sample has been slowed down over time!!.
