“Syn Chron” is an installation designed by Carsten Nikolai back in 2004. He wanted to create an integral sculpture of light, sound and architecture. The crystal-shaped object has a translucent skin on which lasers beam animations insync to the sounds. You can also go inside the object to get the whole light, sound and space experience. Indeed it’s that big.
Gestalten.TV has a video where Carsten Nikolai talks about his work, more precisely about grids and his book Grid Index. You can watch it here.
