Something different
I can think of it as a new submerged city or a nascent world. The truth is that the power of imagination is infinite and when someone believes in it that power will have the opportunity to do great things.
For example, George Lucas, when he made Star Wars, caused a breakthrough in science fiction movies. Possibly, that was not his intention while presenting good and evil in a clone war in outer space. However, Star Wars was a turning point for world cinema.
I can also think of Walt Disney in the making of Snow White and the Seven Dwarfs. It's amazing how much imagination, passion and work he has in this film. The movements, the shadows and the backgrounds, everything is extraordinary if we place ourselves in the era when he made this film.
The Wright brothers also believed in science and art. That's how they made the prototype of a machine to defy gravity and fly.
When one thinks of art, I am reminded of Monet and Impressionism or Dali and Surrealism. They, like many other artists, saw the world differently and represented it with art.
The list of artists who saw and did something different is very long, but I cannot stop naming Leonardo Da Vinci. He was an innovator, an inventor, an artist and a scientist. All his works are full of passion and changed the way we see the world.
I am not comparing @xpilar with these artists but I do see that he does something different. He has the same tools that we have: a computer, a color palette, knowledge of geometry, etc. However, he has the ability to create an authentic spatial vision. He's creating something new. His imagination is free and undoubtedly has the power to transform.
Together: imagination, perseverance and belief in oneself bring about innovative concepts in art. I do not know if I am in the presence of a great artist but I do know that he is showing something new and different that gives the audience the possibility to rethink the present time and future time.
