秋千时光是马萨诸塞州会议中心管理局城市更新计划“D上草坪”的一个临时装置。秋千时光将功能和美融为一体，突出了能源利用与游乐，以及能量生产与消耗的方式。这个城市游乐场由18个悬挂在特制太阳能顶篷下的旋转浇铸成形的聚丙烯秋千组成。秋千时光采用独立的供电系统，消耗由一系列光伏电池收集的太阳能，这些电池同时又会将紫外线转化为电子照明。

这个游乐场会实时响应环境的状况，并以照明体现每天收集的太阳能。整合在顶篷中的光伏电池会在白天收集和储存太阳能。整合通过自动化系统，积累的能量将传给秋千内的LED灯。这种“直接驱动”的用电方式使能量的消耗与生产保持一致。每个秋千内的加速传感器可直接响应使用者的加速力和倾斜度。当秋千从静止开始加速时，微型控制器就会按从白到蓝、再到紫的渐变过程调整LED显示。

秋千时光的响应元素让使用者相互交流并与秋千互动。公众娱乐由此形成了一个社区实验室，并提高了人们关于能源消耗和生产的意识。秋千时光将紫外线转化为视觉效果，显示出太阳能的充足和利用情况。（尚晋译）

Swing Time is a temporary installation located within the Massachusetts Convention Center Authority's urban renewal initiative, Lawn On D. The integrated functional and aesthetic properties of Swing Time foreground energy use and play, as well as a means of production and consumption.The urban playscape is composed of 18 roto-molded poly propolene swings, which hang under a customfabricated solar canopy. Swing Time uses a standalone power system that generates and consumes solar energy harvested from a series of photovoltaic cells that translate UV rays into electrical illumination.

Responsive in real-time to environmental conditions, the playscape's illumination corresponds to daily accumulation of solar power. Photovoltaic cells integrated into the canopy capture and store solar energy during daylight hours. Through an automated system, the accumulated energy is disseminated into LED lights housed within the swings. This "direct drive" electrical application allows energy to be consumed concurrent to its production. Accelerometers contained within each swing directly respond to the acceleration forces and tilt exerted by users. As the swings increase in momentum from a static position, a microcontroller adjusts the LED output through a gradient scale from white to blue to purple.

The responsive elements of Swing Time invite users to interact with the swings and with each other. Public play creates a community laboratory and raises awareness of energy consumption and production. Swing Time translates UV rays into a visual register that indexes the abundance and applications of solar energy.
