The name is tricky, though. What shall I call the artist? dotdotdot, ..., tripledot?
Or Ellipsis: "a mark or series of marks that usually indicate an intentional omission of a word in the original text. An ellipsis can also be used to indicate a pause in speech, an unfinished thought, or, at the end of a sentence, a trailing off into silence. When placed at the end of a sentence, the ellipsis can also inspire a feeling of melancholy longing. The ellipsis calls for a slight pause in speech." (Wikipedia)
Or maybe Securitas inverted? As the security company Securitas use a similar logo of three red dots on a black background.
I settle for dotdotdot, that is the easiest one to understand and pronounce.
Have a look at dotdotdot's work:
