Speaker 1 (00:05):
This is data Specialist standers of the Data Redundancy Project
SCP six zero three object classes safe special containment procedures.
As of December eleventh, two thousand six, SCP six zero
three is stored on a dedicated computer system in Laboratory twelve,
a Observation Room one. The system may be accessed remotely

(00:28):
via Foundation intranet. Personnel wishing to access SCP six zero
three must apply for a temporary password to allow them
access to the system. A standard SCP six zero three
password will expire twenty four hours after being issued. If
access to SCP six zero three for longer than twenty
four hours is required, please contact doctor Brown. Physical access

(00:52):
to Observation Room one without direct authorization from doctor Brown
is prohibited. SEP six zero three should never be left
to run unattended. Description SCP six zero three is a
self replicating computer program capable of reproducing and extending its
own source code. The first version of SP six zero
three was written in nineteen ninety six by redacted, a

(01:15):
graduate of redacted University. Redacted's personal computer was seized by
the Foundation in nineteen ninety seven following an investigation into
multiple anomalous occurrences. In a two thousand three interview, Redacted
claimed that the original source code for SCP six zero
three consisted of approximately twelve thousand lines of anc slash isoc.

(01:40):
This claim has not been verified. On startup, SCP six
zero three begins generating new versions of its source code
in a separate thread of execution. SEP six zero three
does not modify itself in memory. Instead, it keeps an
internal copy of the source code, which is modified in stively.

(02:01):
On a clean termination of SEP six zero three, the
entire source code will be output to the working directory
in a new directory named source. In addition to modifications
to the internal and external functionality of the program, alterations
and additions to the semantics and structure of the language
are made with each iteration. Due to its continuously changing nature,

(02:24):
the language has been nicknamed Morphic. When passed a list
of source files, sp six zero three acts as a
compiler and linker. Morphic code is always compiled by the
version of SEP six zero three by which it is output. However,
older versions of the program can rarely compile code output
by newer versions. On compilation, the program is output to

(02:48):
an executable file named megaprime. Recent versions of the SAP
six zero three source code consist of approximately seventy million
lines of heavily obfuscated morphic. SP six zero three builds
are archived on redacted. The latest build is redacted. For
information on building SCP six zero three, see document redacted.

(03:12):
When left to run uninterrupted, SCP six zero three will
generate prime numbers increasing from two and print them to
the environment's standard output. Upon hitting a super prime, there
is a chance that a GPU accelerated window will open.
The contents of this window are varying. This process is deterministic.

(03:33):
The same version of SEP six zero three will always
open a window at the same superprime and display the
same scene if the scene accepts any form of input
from the user. Entering identical input on separate executions will
give the same result. Most scenes are accessible from only
a single version of the program. However, some scenes persist

(03:54):
through multiple compilations, often with variations. It is common for
persistent scenes to evolve with each version of SCP six
zero three, though some such as die, have remained unchanged
since their first iteration. The most prominently recurring SCP six
zero three scenes are documented below. Other recorded scenes are

(04:15):
documented in the supplementary file six zero three Dash ft
Dash two zero one two Die sep. Six zero three
Dash forty four Die presents itself as a text based
interactive adventure game. When Dye starts up, the following passage
is printed to the screen. Your head pounds ever harder
as you struggle through the jagged bramble. You gaze back

(04:37):
through the smog at the silhouette of the old lighthouse
to the north. The faintest glimmer of hope, extinguished so
violently by your foolish exploits a distant and unattainable fantasy.
You know you can never return. A prompt appears below
the passage, and the player may input commands and submit
them by pressing the enter key. Entering the command look

(04:57):
reprints the previous passage to the screen. Attempting to go
north results in the message you cannot go north. Attempting
to travel in any other direction results in a similar message.
Attempting to perform most other actions results in the message
you cannot do X, where do x is the action
entered by the user. Attempting to perform actions on objects

(05:18):
such as pick up Apple results in the message there
is no Apple here or similar to date. The only
command found to progress the game is die. On entering
the command, the player goes into immediate cardiac arrest, and
the message as the world around you fades to blackness,
you know that you deserve the consequences of your actions
is printed on the screen. This message remains on the

(05:40):
screen until SEP six zero three process is terminated. The
effect of the die command occurs even if the system
is being accessed remotely. If two or more people participate
in entering the die command, all participants are affected. For example,
if one person enters the word die and another presses
the enter key, the hearts of both players will stop simultaneously.

(06:02):
It is not currently known whether it is possible to
win die. If DYE ever starts up during an SCP
six zero three session, it is recommended to simply terminate
the SCP six zero three process. Attempts to resuscitate users
affected by the die command by means of CPR have
been successful. Any further experiments testing the effects of DYE

(06:24):
should be carried out in a staffed medical unit. At
the discretion of doctor Brown Jacob SCP six zero three
Dash twenty Jacob is an artificially intelligent being who appears
as a multicolored equilateral triangle and a black background. The left, right,
and top corners of the triangle are red, green, and blue, respectively.

(06:45):
These colors are interpolated between the two points to fill
the rest of the triangle. When Jacob is active, the
phrase hello world peers in the title bar of the window.
As of February second, two thousand six, users may converse
with Jacob by typing phrases into the input field at
the bottom of the window and pressing the enter key.
Jacob's response will appear in bold white text above the

(07:08):
triangle and remain on screen until it is replaced with
a newer response. Jacob's response will always appear immediately after
the enter key is pressed. When the SEP six zero
three process is terminated, Jacob's memory is deleted. Due to
the psychological distress this is caused. In the past, it
is recommended that communication with Jacob is restricted to personnel

(07:30):
who possess little or no tendency to anthropomorphize. Despite being
unable to recall past events or dialogue from previous sessions,
Jacob appears to exhibit a greater aptitude for language and
learning with each iteration of SCP six zero three in
which it appears history of Jacob. Jacob first began appearing
in a version of SCP six zero three compiled on

(07:53):
January fifth, two thousand two. In these early iterations of
SCP six zero three, it was not possible to interact
with Jacob at all. At this time, Jacob was simply
known as the triangle. On September ninth, two thousand and four,
Jacob was left running for twelve minutes by doctor Brown,
after which the phrase please submit your query appeared above

(08:13):
the triangle in bold white text. Doctor Brown proceeded to
type the word Hello. The program display gave no indication
that the keypresses were being handled by the program. However,
on pressing the enter key, the text above the triangle
was replaced with the word high. A full transcript of
the initial exchange between Jacob and doctor Brown can be
found in the document Jacob Dash zero zero one dot text.

(08:36):
On February second, two thousand six, a rectangular text field
for the user's input was added to the bottom of
the Jacob display. The user's input will appear in this
field as they type. When this change was mentioned to Jacob,
it responded, I can't see what you're talking about. Do
you like oysters? SCP six zero three Dash nine five.

(08:57):
A rapid sequence of seemingly random images is displayed, and
the program's memory usage increases by approximately twelve percent every
second until it passes five hundred twelve megabytes, at which
point this rate increases to approximately thirty one percent a second.
Viewers of the scene become unresponsive to external stimuli of
any kind, usually blocking the line of sight between the

(09:19):
viewer and the computer screen within the first five to
ten seconds will prevent the effects of the scene. However,
prolonged viewing will cause the viewer to remain effected until
the SEP six zero three process is terminated. When the
memory usage of the program passes five hundred twelve megabytes,
affected viewers experience a variety of afflictions, most notably bleeding

(09:41):
from the eyes and throat and rapid, severe wrinkling of
the skin behind the legs and arms. Many viewers will
involuntarily evacuate their bowels. SEP six zero three will crash
if the system runs out of available memory, at which
point affected viewers will normally fall unconscious. The viewer. Doing
of screen recordings taken of sc P six zero three

(10:03):
DASH nine five have shown to have no detrimental effects
to the viewer except those who suffer from photosensitive epilepsy.
