Sound made by a small electric motor cranking and reversing a lever (on an infant's glider/sleeper). This take has multiple repeats of the sound (a different take i have here provides just one repeat of the sound). If you pitch-shift this down about six steps and add a metal/plate/hall reverberation effect, it sounds remarkably like a sound you hear in the carbonite chamber scene in the empire strikes back :). This was recorded with a sony icd-st voice recorder held next to the glider, then noise removed with an audio tool, then normalized. I request but don't demand credit to me (richard alexander hall) for any use of this sound.
