Double S Braille

This iteration of the monogram sees another couple of abstract S's, but this time it has origin in the Braille system.

"The Braille system is a method that is widely used by people who are visually impaired to read and write, and was the first digital form of writing." (Quote from Wikipedia)

The upper left image shows 2 Braille S's (three dots each) and the lower right the monogram with the same abstract and simplified letters.

Like before, this should not be obvious.
