The concept is an interactive lighting installation that is intended to be incorporated into the glass box, where passengers sit and wait, at a train station. The walls of the glass box are lit up with LED lights there basically always lit in one color. When a passenger sits on one of the benches, one changes section of the light color, so that there are now two colors that light up.
If another passenger sits on one of the benches, another section will change color so that the glass box is lit up by three different colors. When the passengers get up from the bench, change the color of the light back to the standard color. The glass box will thus have one expression if no passengers are sitting on the benches and it will change expression in time with passengers sitting down and getting up from the benches.
