Slide Whistle Blower - eerie sound machine

Check out this unique and creative slide-whistle blowing machine.

From the YouTube description:

The movement and the air for the whistles comes from an old hand-cranked forge blower; the different gear ratios of the axles makes the pattern pseudo-random-ish. I have not calculated how long it will take for the pattern to repeat.

You'll be able to check this out that the upcoming (and very excellent) Maker Faire.
