    $\begingroup$ So I took each of these characters' hex value and converted them to decimal. And I'm nowhere. imgur.com/lWEDhW2 $\endgroup$ – Raystafarian Nov 14 '14 at 14:17

    $\begingroup$ @Victor re your fisheye, the pattern becomes 16/2/15/3 - or 18/18 $\endgroup$ – Raystafarian Nov 14 '14 at 14:43

    $\begingroup$ I feel like the double fish eye symbol is the separator. The it makes an even 16 symbols. I dont think simple substitution works here because the words are too small. it may be a block cipher since 16 is a square number. $\endgroup$ – stackErr Nov 14 '14 at 15:47

    $\begingroup$ @stackErr but the second set is 15, not 16 $\endgroup$ – Raystafarian Nov 14 '14 at 15:54

    $\begingroup$ @Raystafarian Theres three fisheyes at the end. I am considering one to be in the ciphertext and the double fisheye as the separator. I could be totally wrong as well :/ $\endgroup$ – stackErr Nov 14 '14 at 15:57

It's morse code, with every circular symbol representing a dot and every other symbol representing a dash. The content of the symbols is a red herring.

    $\begingroup$ @augustin you might like the mutilated chessboard problem. It's a similar "projection" problem, where the answer comes about pretty quickly if you can figure out which information to ignore, and which information to keep (project). $\endgroup$ – Joshua Taylor Nov 15 '14 at 16:05
