(Here, I've concatenated all the data starting with lengths, then inner, then outer colors in the order of the pattern. This is just ONE of a many ways of concatenating the data. Just for demonstration purposes, I used a base 58 alphabet here and use ? when the value goes beyond 58. By no means is this a complete list).
Have you tried using the inner shape as the third bit (skinny line or blob of paint)?
Each inner flame is either a blob or a line.
Inner Color, Outer Color, (Line/Blob)
8 variations of flames taken in pairs. 76 pairs of 64 variations.
I still think we are looking for a BIP38 encrypted key starting with 6PR.
Update on this one, there appears to be another channel of info we've been ignoring (or not talking about publicly on this forum). Props to smracer for noticing it. If you view the "skinny/fat" inner flame as another channel of data, then there is an *almost* 16 digit match between the outer bottom height and it's skinnyness. Flame # 9 counting r 2 l along the outer bottom doesn't match with this otherwise perfect match. The interpretation of the skinnyness is a bit more subjective than the others but once you've spent some time deciding between them it becomes easier to call. This track contains the weird solid red flame most have been ignoring. See for yourself and let me know what you think. Perhaps we could compare our skinny/fat calls and start using this new channel of data for playing around with... Not quite as solid a lead as alphabetcannary's discovery but I think it's significant.
There might be one more channel of data not picked up on yet. I'll let you know once I've poked around with it a bit.
