Modern technology pushes the speed of communication between people to its limits. Meeting friends over web cameras feels almost like sitting in the same room. The signal that gathers us at this virtual table, and vast amounts of data transmitted to space and back, seems imperceptible. With ”Flux”, the technical aspects of digital interaction were also pushed to the maximum. A system, both in software and hardware, was built to use the highest potential of programmable LEDs on a large scale. The whole show runs by code, and is tightly synchronized to the spatial sound score. With a tubular shape rising to the clouds, four high-speed cameras and an eight-speaker sound system an immersive experience which reveals hidden algorithms that shape our online encounters at the speed of light was built.
