Night of Lights was a group solution to the challenge of creating a design intervention in a public space. We chose to use the circular pool in Madison Square Park to stage our interactive event, and took advantage of the pool’s constant circular motion to create the dynamics of the interaction. One evening, we set out hundreds of tea lights in small floating containers around the pool. People passing by could stop, light a candle, and place it among the group of floating candles. The event was a huge success; passersby were attracted to the elemental and spiritual quality of the floating candles, and we even had a few local artists come and play music to accompany the event.
