A project I've been working on for some time that combines a readable writing system with a means of creating decorative streams of symbols, allowing for practical or artistic use. It is designed to be writable in the same way as English, with a couple key differences:

end of sentence within a thought:
. = SPACEBARx2
? = ?SPACEBAR
! = !SPACEBAR

end of thought:
. =SPACEBAR-
? = ?-
! = !-

end of paragraph:
. = .
? = ?-
! = !-

numbers:
numbers at the beginning of a sentence = ###-SPACEBARtext
numbers at end of sentence = textSPACEBAR-###SPACEBAR-
Use as applicable to avoid numbers and letters bleeding into each other.

For purely artistic streams of writing, Start every sentence with a capital, skip spaces, and use '-' as a period. This allows for a smooth bar of symbols without any random bits jutting out that can be used for framing or backgrounds.
