"S.T.A.Y.", in morse code "... - .- -.--" is a tribute to my favorite film "Interstellar", directed and produced by Christopher Nolan and to my favorite composer Hans Zimmer who produced the music for the film.
This fractal resembles me the structure of the tesseract in which the final scenes of the film take place.
In the film TARS explains to Coop that the ultra-advanced beings “constructed this three-dimensional space inside of their five-dimensional reality to allow him to understand it”.
Here, time is represented as "physical dimension". Coop sees Murph’s bedroom, from when she is 10 years old, and every moment in that time is presented through infinite physical lines, which Coop is able to travel through and experience.
So what does "STAY" refer to? the answer lies in the film. [5000x6500]
