Momentrium #3 Mars

The new piece of Momentrium series was shown in a big dome called Mariendome in Linz.

This project #3 Mars expresses a real-time position of the Mars. A robotic arm of the object has an illuminated arrow and moves slowly, and the arrow points to the position of the Mars. Sometimes, the robot arm starts to play the record of the complicated movement of the Mars.

The city of Linz is known for a city where Johannes Kepler, who found the laws of planetary motion, lived there in the early 17th century. Although the movement and order of the Mars have never changed in the context of the Earth and the universe, he provoked questions where we human beings were standing on. In a public place of the city of Linz, the illuminated arrow gently asks us a question for what we human beings are standing on the earth, in 21 century.

Changing a doguma is not always easy. However, the changing position of the Mars pointed by the arrow reminds us curiosity for how the world is changing, as Kepler explored.

Kazamidori in a small shop (Ars Electronica Festival 2014)

In Ars Electronica Festival 2014(September 4-8, 2014), the city of Linz became a big museum consisted of micro exhibitions of art projects. Our Kazamirori was shown in a show window of a small stationary shop in Linz.

Momentrium #2 Future Test

We are currently working on the new work named Momentrium #2 Future. This kinetic art by illuminating arrow will point at the directions of the Future. If you approach to this object, the arrow will realize you and will be guiding you to the next direction. The Momentrium is a series of lighting arrows in different size and movement. The arrow represents directions of invisible force where we can’t reach physically.

TRIART is an experimental art project to realize new expression by combining Triathlon and Art. This TRIART was conducted in Sunport Takamatsu Triathlon 2012. (

In this project, we realized both TRIART LOG and TRIART INSTALLATION. The TRIART LOG expresses individual stories of participants, by printed picture roll expressing a story while they were in the game. On the other hand, the TRIART INSTALLATION expresses a collective art to express a moment when the first athlete reached to the goal. In this installation, it expresses all positions as if a gathering photograph from above.
