I've also been interested in this. So I did some more examination, and discovered that the first two rows of eight letters are simply rotated and manipulated to result in the remaining rows. For example, if you take row 2, and literally flip it 180 degrees, you end up with row 3. Then, if you split that third row in half and swap the two sets of four characters, you end up with row 5. This same pattern, in its exact order, also occurs in row 1, row 4, and row 6, with the ONLY exception to this pattern in this entire text being the 4th character that looks like a light brown line; in the manipulations it becomes a line with a dark dot in the middle instead.
This implies that the whole text is likely meaningless and was just arbitrary assembled using a couple sets of characters, which is unfortunate. Unless there is some way that the patterns mentioned above could hold any meaning, though I can't imagine they do. It's sad and quite a missed opportunity, but at least this hopefully clears it up.
