 In 2004, Yamagata held a laser installation, “Quantum Field X3” at Guggenheim Museum Bilbao, Spain.In this exhibition, the laser which was coming from a disk shaped object set upon a hill aside the museum reflected and lightened up two cubic buildings’ walls surrounded by holograms which were set outside of the museum.Starting from the exhibition in Yokohama, Yamagata's world of laser installation began to expand in scale.
