In the theater in Plzeň, there is an installation by the Japanese artist Ikeda

Plzeň - Japanese audiovisual artist Ryoji Ikeda today presented his sound and light installation in Plzeň. Interested individuals will be able to not only hear and see it, but literally perceive it with their whole bodies until August 11. The performer and composer of electronic music brought his installation to Plzeň as part of the European Capital of Culture and the Japan Fest 2015 project.
Ikeda's performance is considered the highlight of this year's Japan Fest, and fans of cutting-edge technology, multimedia art, and electronic music view his participation in Plzeň as a small sensation. As stated by the director of the Japan Fest exhibition, Ivo Hucl, during the opening, Ryoji Ikeda is an artist who has managed to combine the cold rationality of the latest technologies with lyricism and deep emotions, scientific theories with art. Despite the nature of his installations, they reflect, according to Hucl, the traditions of Japanese zen. He offers the audience an encounter with themselves, he said.
Ryoji Ikeda was born in Japan but now lives and works in Paris. Through his music and installations, he explores the fundamental characteristics of reality and sound. He often uses tones and noises at the edges of frequencies perceivable by the human ear; some are only recognized by the listener moments after they have faded away.
For Japan Fest 2015, this acclaimed artist prepared an installation titled test pattern [n°7], with which, according to the organizers, he explores or tests the limits of the performance of contemporary digital technologies and human consciousness perception. Therefore, organizers do not recommend attendance to those sensitive to sharp flashes, rapid light changes, and intense sounds.
The projections are based on electronic music that plays simultaneously with them. They are characterized by constant movement and the alternation of black and white colors. Some participants are driven to dance and move, while others lie on the floor and let the sounds and light affect them. This was also the case during today's opening in Plzeň. The projection with music lasts several minutes and repeats in a loop for the entire duration of the gallery's opening.
Test pattern is a system that converts any type of data, including text, sounds, photographs, films, or music into graphics resembling barcodes and binary patterns made up of zeros and ones. This way, the visitor is drawn into flickering, pulsating, and shifting light patterns while simultaneously experiencing sound, which ranges from clicking to computer sounds to deep rumbling.
In Plzeň, Ikeda prepared the seventh installment of this installation, which has already taken place in Sydney, Paris, Madrid, and New York. For the small stage of the New Theatre, he prepared a more intimate version within a space of 14 x 14 meters with a floor projection.
