Braille music. I've already converted the braille into music, which gives me.. BC-AGCEBA (- being a rest)
I've also converted it into actual music which you can hear here
I know it may be nothing, but the braille gave me EXACTLY the correct number of notes for 2 bars of music... Also the note lengths seem to go in a run of 8th's and are consecutive pairs, which provide a meaningful tune, they don't seem to be completely random.
Just some thoughts and I'll be trying to translate this in a variety of ways since the image may have been mirrored, etc.
