You should send someone out into the streets every day, all day long, and have them write blog entries. Different streets, of course...not just downtown and Cap Hill (and Green Lake).
There was an young hipster who swallowed a bird;
How absurd, to swallow a bird!
He swallowed the bird to catch the spider
That wriggled and jiggled and tickled inside him.
He swallowed the spider to catch the fly.
But I dunno why he swallowed that fly -
Perhaps he'll die
Not to be a cantankerous old cuss, but a pure, unwavering tone sounds like a sign wave. Unless you modulate it with an additional much lower frequency sign wave, then you would get the warble. Sorry to get all audio-science-nazi on you, but that ridiculous graphic that Google is passing off as a modified sine wave in honor of Heinrich Hertz's birthday still has my dander up.
