Item #: SCP-551
Object Class: Safe Keter (Recategorization approved Sept. 7, 2009)
Special Containment Procedures: SCP-551 is to be contained in a locked steel box. It must be of an adequate size to carry all pieces of SCP-551. The box should be stored in a high-security Hazard Vault on Storage Site-23 and at least two (2) Level 3 staff members are to approve any neutralization requests prior to its removal. SCP-551 is not to be removed from containment except in the course of an approved neutralization attempt.
Description: This description is void as of September 2009: SCP-551 is a standard, five hundred and fifty (550) piece jigsaw puzzle, which should depict, in its finished form, the image of a solitary woman on a small row boat, surrounded by a stormy sea. However, due to the nature of SCP-551's abnormal qualities, some details of the scene are left incomplete, such as the woman’s face and [DATA EXPUNGED].
Due to the events recorded in Incident S-K 551, SCP-551 now is a standard, four (4) piece jigsaw puzzle, which depicts, in its finished form, the image of flotsam drifting on a stormy, black sea. The rotting remains of a woman's head are impaled on the largest piece of driftwood in the scene.
SCP-551 was found in the apartment of ███ ████ after other residents complained of an odor seeping out from under the door. The severely malnourished body of ███ ████ was discovered beside SCP-551, with several pieces still clutched in her hand. Roughly one third of SCP-551 was pieced together on her floor.
Multiple subjects testing SCP-551 stated that a completion of the puzzle seems inconceivable. The mental reactions of subjects to SCP-551 was diverse, apparently depending less on the puzzle and more on the personality of the subject (see Addendums 551-1/2/3), though the effects of SCP-551 on the psychology of subjects should not be overlooked.
Standard Class-D personnel is tasked with piecing together SCP-551. Subject spent two weeks in a single room, trying to finish the puzzle, and pausing only to sleep. Subject became increasingly frustrated with his progress on SCP-551, which failed to span past forty (40) connect pieces after this time. Subject slept less during his last days working on the puzzle, and was permitted to stop when he [DATA EXPUNGED].
Class-D personnel with a history of addictive behavior is tasked with piecing together SCP-551. Subject acted aloof about the assignment at first, but after connecting two pieces, she seemed to become alarmingly obsessed with SCP-551. Subject stayed beside it for days, sometimes screaming about her lack of progress. After a period of four weeks, subject lost consciousness from lack of sleep, and the test was ended. One hundred and two (102) pieces of SCP-551 had been connected.
Dr. ██████, who scored above average on a standard IQ test, expressed scepticism about SCP-551 and was approved to test it. Dr. ██████ completed all but a couple of sections, specifically the woman’s facial features and [DATA EXPUNGED]. Despite this success, Dr. ██████ showed confusion over his remaining pieces and adopted a fatalist attitude toward the puzzle, finally refusing to complete it after four days.
A computer-based approach was taken on the completion of the puzzle. The first tool used was a mechanical arm designed to take a piece and place it in the puzzle, used along with a camera and a desktop computer running an image processing algorithm. The application was tested extensively with normal puzzles; however, when tasked with completion of the puzzle, it would invariably trigger a blue screen or a kernel panic as soon as it finished scanning the piece. An embedded design approach was taken, and the computer was replaced by a microcontroller in charge of moving the piece linked to an image processing DSP; however, the value of the program counter register in all the CPUs would corrupt as soon as soon as the DSP finished scanning the picture of the piece, and in several ocasions a sudden, unexpected current peak would result in damage to the CPUs and other components. Automated solutions, therefore, had to be discarded.
Dr. Alexander Laito of Site 23 requisitioned SCP-551 for testing, and managed to successfully complete the puzzle on September 5, 2009. Incident S-K 551 then occurred, leading to the deaths of over 100 Site 23 personnel, the breach of two Safe Rooms (338 and 512), and property damage that has yet to be tallied. Upon the conclusion of Incident S-K 551, SCP-551 assumed the shape of a four-piece puzzle with an altered image, and the difficulties in piecing it together vanished. SCP-551 now exhibits an apparently mild psychic effect, encouraging individuals viewing it to finish the puzzle.
