Digital exhibition is virtually underwater

The experience was created by blending projection mapping, computer graphics, digital art, lights and videos-typical of works by the Tokyo-based creative art group.

"There's no real, tangible thing in the show except the water, it's all made by technology," says Ryotaro Muramatsu, who founded Naked Inc two decades ago with a view to provide computer graphics for the film industry.

Although he has created an undersea world, Muramatsu prefers to stay on the surface, swimming and surfing, or as he puts it, "riding the waves".

The actor, film director and artist says he wants to create an experience that will allow people to feel life in virtual world and possibly prompt them to think about the question: What is real?

He expressed his worries that in the future, people may get lost in the virtual world when the technology is highly developed.
