a little set of functions I've been using to create "glitchy" strings.

And the evening and the morning w for meat: and ie the

And the earth was without form, and void; and darkness was
upon the face of the deep. And the Spirt it was good.
And God said, Let us make man in our image, after our
likeness: and let them have dominion over the fish of the
sea, and over the fowl of the air, and over the cattle, and
over all the earth, and over every creeping thing that
creeind: and God saw that it was good.

And God called the dry land Earth; and the gathering

days, and years:
In the beginning God created thnd God divided the light

And God said, Let there be heaven to give light upon the
earth: and it was so.
And God made the beast of the earth after his kind, and
cattle ere whose seed was in itself, after his kind: and
God saw that it was good.
