OT: Hey You Weirdos!

Hmmm... This is all most interesting... I kinda like the infra-sound plant but it's a wee bit to 'techie' for the feel of my story. Though perhaps sneaking into the cities computers and making them think that the street outside her apartment needs digging up at 2am might do the trick. Hadn't thought of sleep deprivation, that might be neat.
BTW, the drugs thing is mainly to be administered to people around her, when I said 'destroyed the person he loves' I was referring to emotionally as opposed to physically fubar'd. Since the drugs are to be 'taken' by others then whether or not they're traceable isn't terribly relavent. What about PCP? I've heard it does seriously nasty things to a person, but other than that I don't know too much. Drugwise I'm looking for something that will make someone very violent and aggressive with a single dose.
As for poisons, they won't be getting used until 'endgame' and I'm mainly looking for something relatively fast acting (5-10min after ingestion), and tasteless. Whether or not it's traceable is irrelavent. Keep the ideas coming, this stuff is great! In a sick twisted depraved kinda way anyway.

Have you never hooked up a high frequency signal into a speaker in a tech class?
Pitched high enough that the teacher can't hear it due to age, but some of the students can?

Quite entertaining to watch, but does get on your nerves after only a few minutes; even if you turn it up enough that can't hear it personally.

You could probably introduce an inaudible squeal to a gift radio without adding components if you googled the right things.

Sounds worse than the old computer monitor hums. Those and TV sets always used to bug me.
