De verkar inte vara.

Det finns en stor (ish) artikel om rörelse om det, efter att ha skannat igenom det här hittade jag vad jag tycker är den viktigaste delen.

If you Google the Braille alphabet and try to read along, you'll discover a problem that I ran across as well. Some of the more distinguishable symbols do not appear. They just aren't letters. At first I thought they were placed on the wall upside-down or printed backwards. That would be embarrassing for old Dr. Wells. Then I remembered to check Second Grade Braille. This is your cool lesson of the day. Braille has a system of contractions in addition to the alphabet. Certain symbols can mean letters, prefixes, suffixes, or common words. So, those symbols that I wasn't able to identify are Second Grade symbols. However, with a poor idea of where sentences and words start on the wall, I still wasn't able to decipher anything meaningful. Two symbols that appear next to each other a lot could mean "-ed as" or "-ed z." Deep stuff.

Senare säger artikeln att det verkligen finns viss mening men vi kan inte vara säker på vad det är.

Of course, I could be accidentally insulting The Flash's art department. Perhaps this is supposed to mimic Braille, but doesn't actually say anything and I'm just being an over-analytical jerk. They could have put a panel in upside-down for all we know. Maybe it's not Braille at all. But it definitely is some sort of pattern that's too significant to ignore.
