Flynn Digital Soldiers image decoding idea…
I coded the light red or pink as 0, medium red as 1, and dark red as 2. Going through in ternary from 000 to 222, with 000 as a space or null character and 001 as A through 222 as Z, I got the following from the graphic, reading left to right in triplets, then starting at left again on each new line, from top to bottom:
HPMCJNLJJDCKLJMTOLPMVPJDNCMJDNCNCMMUPDMS
Then, I used a substitution cipher because the Vignere didn't pop up any results that seemed coherent. I did use obvious keys to attempt to decode it, then some random keys and got nothing. So, with a substitution cipher I got this: 1=original, 2=substituted
(put it in a text editor with a fixed width font if you want it easier to compare, they do line up)
1=HPMCJNLJJDCKLJMTOLPMVPJDNCMJDNCNCMMUPDMS
2=WASINTENNOIDENSUREASMANOTISNOTITISSHAOSB
Spaced out: WAS IN TEN NO IDEN SURE AS MANOT IS NOT IT IS SHA OSB
It's almost coherent. I'm not sure what some of the abbreviations mean. If you add spaces in different places, you could get different words, though.
I've been up all night researching, so my eyes are crossing at this point. Take this for what it's worth. Maybe some other Anons can build on, work with it further.
