I'm writing this from the train as
I approach the facility. I intend
to update this analog journal
throughout the duration of my
assignment. My colleagues find it
\"quaint\" and \"rustic\" but I
honestly prefer taking notes this
way.

This project is big.  It will be a
career defining achievement if it
is successful."
                 "Week 1

Subject has awoken and is slowly
adjusting to their isolation
chamber.  Frequent banging on the
wall and screaming has reduced to
the occasional groan.

I'm adjusting in my own way.
Biggest problem so far is there's
no way to heat up water for tea.
And I locked myself out of the
terminal several times the first
few days.  Difficult to focus when
the subject is stressed.  Should
get easier from here now that it
has calmed down, but just in case:

dmlydHVvdXNtaXNzaW9u"
                 "Week 2

Subject showing signs of progress.
Isolation treatment has heightened
the senses, just as predicted.  It
cannot communicate yet, but I know
that it can sense my presence.
When I approach the door, it often
follows.

If this trend continues, I'm
certain it will make contact in a
week's time.  What will it say?
The whole team is excited, but
they don't have to spend every day
down here monitoring it.  It's not
easy to watch over something that
is deprived of nearly everything,
but if we don't do this, the other
guys will."
                 "Week 3

\"Let me out.\"

That's what was displayed on the
terminal.  The subject's first
communication.  An organism, using
only its mind, talks to a digital
system for the first time... and
it asks to leave.  Our subject has
no idea of its own significance.
We are on the brink of changing
information warfare forever!

But our experiment does not end
here.  The subject does not yet
respond to my replies.
Bidirectional communication must
be established."
                 "Week 4

\"Hello,\" I said.

\"Let me out.\"

That is all the subject would say
back. \"How are you?\", same
response.  \"Are you hungry?\",
same response.

Perhaps the subject will say more
soon.  We have increased the
sucrose level in the ration as a
reward and enticement for further
communication."
                 "Week 5

The subject has been silent.
Changing nutrient levels in the
ration has no effect.  The subject
no longer approaches the door when
I do.  Vital signs all normal.

The whole team is starting to feel
stressed.  I'm having strange
dreams and waking up frequently.
I'm exhausted, but if I report
these experiences they'll remove
me in an instant.  Too many
resources have been poured into
this to allow an insomniac to
screw it all up, and I've worked
too hard to let someone else take
the credit.  Failure is not an
option."
                 "Week 6

The subject is still silent.  The
directors wanted to call off the
experiment and euthanize the
subject, but after some
negotiating I got them to agree to
two more weeks.

I still haven't told anyone about
my dreams.  Every night is the
same.  It's pitch black.  All I
can hear is the faint sound of
footsteps.  I can't move.  The
footsteps grow louder and louder
until I can feel a presence just
in front of me...

Then I wake up."
                 "Week 7

It's clear what is happening now.
The subject has transcended our
interface and is injecting
thoughts directly into my
consciousness.  It's theoretically
possible, but the isochamber
blocks all signals except for the
terminal interface.  The only good
news is that it appears incapable
of reading my own thoughts.

Did I make a fatal mistake?  I
need to turn this around fast."
                 "Week 8

I've failed.  It's all over.  The
Directors shut it down.  A member
of the medical team removed a
small cartridge from the
refrigerator, inserted it into the
control panel, and typed some
command into the terminal.
Subject's pulse flatlined within
minutes.  I've been given some
time alone to pack up.

I may be a failure but shouldn't I
feel better with that thing out of
my head?  I still can't think.  I
can barely write.  I feel
