I'm having trouble reproducing the length XOR decode. My understanding from crax0r's breakdown is: you concat the length bits in this order:

Inner Bottom, L2R
Inner Left, T2B
Inner Right, T2B
Inner Top, R2L
Outer Top, R2L
OuterBottom, L2R

Based on this, Inner Bottom L2R is

XOR'ing with 011010 (starting with second bit) gives us:


Then we run that through the v2 Bacon cipher, (omitting a character?)


Or, if we don't omit any characters and simply take them 5 bits at a time:


And/or shifting 1 so 00000 = nil but 00001 = A. Regardless, I can't reproduce any of the patterns here.
