Are you looking at a still image or the video? The text is blindingly obvious to me in the video, while I'm having serious trouble seeing "Written In Ghost Text".

But a still frame doesn't contain the information necessary to see the actual message, so when it's paused, I can only barely see something which I suppose says something along the lines of "written in ghost text".

Have you ever visited the cloud city of Zalem, by any chance? Got any interesting tattoos done on your forehead?
