the flames on the borders could be binary. long flames representing 1, short flames representing 0. Where to start is the question. Or purple flames being 1/0 and green flames being 1/0. Could be a double message between these too, but again where to start? The outside border looks more chaotic then the inside border. The likelihood of there being a message contained with in the inside border is greater then the outside.
Starting in the left top corner on the inside border you get the following going clockwise:
(TOP) 0110110110 LEAF 100010110110110011
(RIGHT SIDE) 110111110110110111110010
(BOTTOM) 100011100010110111110111110111110
(LEFT SIDE) 011100 LEAFTAILLEAF 1101 LEAF 101
All together it looks like: 0110110110 LEAF 1000101101101100111101111101101101111100101000111000101101111101111101111100111
