Toshio Iwai about Time Stratum III: "In this work, in order to achieve a greater scale of 3-dimensional effect, I used 3 acrylic domes to place hundreds of moving shapes. I used 4 computers, one for the real-time performance of music and sending the synchronisation signals, and other 3 for making strobe lights in synch with the music.
I animated images of animals, plants and minerals, one in each of the three domes."
