The Fifth Dimension

It was quite slow at work this morning so I managed to get a bit a reading done in preparation for my final undergraduate project in Quantum Information. I am also reading "The Science of Interstellar" by Kip Thorne and, whilst mucking around with the iPad's Photobooth during a period of procrastination, found that this reminded me of how the Fifth Dimension is depicted in the film. Thought it looked kind of pretty....any ideas what it is?
