Hi, Natasha. You're not seeing dots, but apparently it's not Braille either.
For a longer answer here's what the artist said about the topic:
"As with the name and the imagery associated with this project, I want things to be open-ended. I want to create a framework for people to project their own ideas and meanings onto. These things have meaning to me personally, but they are what you make them. At least that's how I want it to be. At the core, the dots were a way to remove all names from the posters and covers. Typefaces are loaded with meaning; they imply a time period, evoke ideas of brands, they define too much. I wanted a recognizable symbol that encapsulated the idea of Tycho and ISO50 as a holistic audio / visual project but which didn't imply anything about it. I wanted a kind of glyph that could have come from any time. I don't want there to be an intrinsic meaning to the dot symbol, defining that is best left to the individual I think.
I can tell you one thing, it is not braille and was not derived from braille, as some have posited. My dad was an engineer in the 60s when they were still using computers with punch cards for programming so those things were always laying around the house so as a kid I would collect them and obsess over their meaning. I felt like I had some alien manuscript or something."
