The term "digital art" is used by Inoko to describe teamLab's work, because it is different from painting, sculpture, installations and even multimedia art.

Speaking about how he came up with the term, Inoko, 41, says: "I googled digital art online and found that nobody used it to name their art. So I decided to use it."

But he adds that if anyone offers him a better term he would gladly accept it.

Most of teamLab's works, now on display at the Mori Building Digital Art Museum-an exhibition space dedicated to teamLab's works-aim to erase the line between people and nature, art and viewers, and humans and technology by using lights, sounds, projections and motion sensors.

At the digital art museum, which is bigger than a football field, in the Odaiba area of Tokyo, 470 projectors and 520 computers are used to produce 60 digital works. And among the exhibits is a waterfall several meters high that cascades down the wall onto the floor and disappears around the visitors' feet when they obstruct the flow of water.
