What the hell, man. I saw this out of the corner of my eye and thought it’s the Java logo. Then I actually look at it and think to myself that it doesn’t look like the Java logo at all. Then I read the text and it also jokes about it looking like the Java logo.
I guess, it’s the colors and swirly lines and being vaguely cup-shaped?
