It is incomplete , but i put it on the sandbox. http://scpsandbox2.wikidot.com/5tr4 How good is it so far? Don't forget your binary to text converter!
All this SCP has going for it is being an excessive format screw. All flash, no substance.
A format screw ideally should enhance the strengths of an article, not replace them. In this case, if I have to dig out a binary text converter and a Vigerine deciphering program to read your article, there better be more to the SCP than just "it encodes data about itself at random using existing ciphers through an unknown process."
If someone wants me to start digging up something for fun, it should be a treasure chest, not the sceptic tank.
Furthermore, your draft lacks the Special Containment Procedures, a fundimental part of the format. You can find the format under the "templates" tab in How to Write an SCP.
For this draft, I suggest you get a clearer understanding of what you want this SCP to be or do beyond just randomly encoding itself before working on it any further. Otherwise, toss it and work on something else.
Could somebody try to do this idea better than I did?
What you're doing kind of reminds me of these two. It can control information about itself. Remember though, unless it's like the case of the toaster, you're writing from a researcher's point of view. Write normally and maybe make a point of saying that the file is strictly a paper copy due to the scp changing too much of the electronic copy. In that case, you could then include a physical description, containment adequate for it, etc. Good luck though.
