    I did think about that, but it would require a whole lot of setup getting there. But yes, looking at them trying to figure out what the heck is going on would be priceless. Using just the Piezo horns set a limit on what sounds to make as well. Guess they are rated for 4-20 KHz.

    But as said, i will give it a shot to see what happens.

    And finally figure out what my old Peavy CS800 amp can be used for.

    That is a great idea because the noise would essentially be their own.

I asked him about it at some point and he said he liked it so much that he took it out when he left. Another friend told me that someone at MIT made & sold fluff balls as "pets" with a similar circuit - apparently it became a tradition that the only acceptable way to disable your room mate's dreep was to drown it in the reflecting pool of the chapel.
    Reminds me of the time some coworkers of mine got one of those timed bathroom smell sprayers and stuck it inside the walls of another coworkers cube. Every now and then she would hear a hiss but couldn't figure out what it was. It was out of the spray juice so it didn't make a smell. I think that would have been even more funny if it still had some.

    Yes, Hypersonic sound is the way to go. We were messing about with some Hypersonic speakers at the UK Laser Meet a couple of years ago, this resulted in me buying one off eBay. They are *really* spooky as you tend to hear the sound inside your head rather than through your ears. As has previously been said, they're quite focusable like a laser but for sound.

    A "Baby Shark" loop would get under anyone's skin.

    I listened to 20 seconds of that "Baby SharK.. You should tried for crimes against humanity in the Hague...

    Then again you could download GrandOrgue, (Excellent Pipe Organ Simulator!) and run pop music midi files through it, with the eight foot and two foot stops pulled with Gamba, Trumpet, and Tremolo stops pulled, as well.

    That would be mean...

    I fully acknowledge the heinousness of my suggestion and agree, it ranks right up there with chemical warfare!

    I guess I immediately turned it up to 11.

    I guess we could start smaller. A loop of Nyan Cat or It's Raining Tacos...
