This idea was born in a dimly lit Chicago train station on a cold winter night.

Several other passengers stood sparsely across the platform, keeping a good distance from one another. Everyone had their heads down and eyes fixed on mobile phones. I wondered if a simple play of lighting could make a difference to the dull atmosphere.

Rainbow Station involves interactive RGB LEDs attached with motion sensors. The LED strips running across the train platform are able to detect passengers’ movements -- an area with less people will be dim and cool colored, while a densely populated spot will be bright and warmly lit. This design is a visual representation of social distance, helping the public perceive themselves in relation to the physical and social spaces around them. The artwork also presents an opportunity for interaction, self-reflection and discovery – how much privacy does one need compared to another individual? Why is it so and what does that say about you?
