Swing Time is an interactive playscape formed of 20 illuminated ring-shaped swings. Howeler + Yoon Architecture proposes to the residents of Boston this new type of park where they can perform physical activities, in groups or individually. Swings are made from polypropylene and are illuminated with LEDs. The luminous intensity of the LEDs is controlled by a micro-controller and it signals the activity level of the swing. Practically, an internal accelerometer measures the acceleration forces of the swing. When they swings are not used, the LEDs emit a white and soft light, and when they are used, it turns to violet that increases in intensity depending on the acceleration. In this way, a colorful lighting effect is created. Via Howeler +Yoon Architecture
