One of my grandmother's antique clocks being wound up a couple times - gives a low, twangy chime. You can also hear the pendulum ticking and the wind up of the chime. Recorded on a sony pcm-d50.
This emulates the sound of accelerating to warp speed or some other crazy fast velocity. Originally a clock and pendulum, modified of course. (during playback, there is a chirping sound, but upon download, it vanishes when played. ).
