what if we took english, combined all the letters into new glyphs, and then made up sentences with that, meaning depending on how you read it the meaning of it changes, what if we rotated the letters too and gave it a 4-directional pattern, you could even do 8-directional but i think that would be impossible to decipher because there wouldnt be enough space in the letter, unless you were to use a very large font size with thin calligraphy. you could probably set up a function with a quantum vacuum that receives words/sentences/paragraphs/letters and then randomizes the alphabet into it. and then you can use a quantum computer and decode the cryptography with the inverse function.
