You can read all the various interpretations from people on the above website, but I personally have my own belief of what the three dancing fishies are all about. They are cavorting to a piece of music by Tchaikovsky, from the Nutcracker. They are making a pretty circle with their tails, while they each make a bubble line. Since the fishies are swimming in a circular pattern, the bubble lines get pulled into a circle on a similar vector to the internal circle made by their tails.
Really, people. Can we just look at the mathematics of the glyphs being made out here and stop trying to make them into otherworldly re-interps of various man made religions?! NO ONE knows who or what is making these glyphs, or why, and I think religion has shown itself to be the great divider (that's your Satan people....)
Let us calm down, enjoy the astounding artistry, and stop trying to make more complications of things that are in all probablility very simple. Remember- WE are the lesser lifeform.
