"Berührung" (german for touch, contact) is an interactive animation, designed for the Deep Space 8K at the Ars Electronica Center.

A visitor generates a particle system when stepping on the interaction area. Every visitor / particle system has its own color, represented by a circle that encloses the person on the floor. If two systems come close to each other — if they touch each other — connecting lines appear on the wall. Additionally, the lines on the wall dance to rhythm of the music.
