加拿大Lateral工作室设计的12个超大跷跷板声光装置被安置于纽约市区。装置名为脉冲（Impulse），位于第37街与38街之间的百老汇大街步行广场，该区段现已禁止车辆通行。这些游乐场风格玩具的长度从16英尺至24英尺（4.8米至7.3米）不等。当游客乘坐时，会触发装置内的声光设施，使装置更亮并发出音乐。
发起该项目的非盈利组织，Garment区联盟说到：“这个沉浸式的‘城市乐器’为游客带来了别开生面的互动体验。通过一系列声光跷跷板，将游客转变为音乐家和艺术家，通过他们的动作使装置做出相应的反应及改变。”

Canadian studio Lateral Office has installed 12 oversized seesaws that light up and make sounds on the streets of New York City’s Garment District. Impulse occupies the pedestrian plazas on Broadway Avenue between 37th and 38th Streets. While on display, the block is closed to vehicle traffic. Visitors are encouraged to ride the playground-style pieces, which range in length from 16 to 24 feet (4.8 to 7.3 metres). The motion triggers lights to intensify and emit musical sounds.
“The immersive urban instrument creates an exciting, playful experience, in which visitors become the musicians and artists through a series of illuminated seesaws that respond and transform when put into motion,” said the Garment District Alliance, a non-profit that organised the project.

每个跷跷板都覆盖有透明的聚碳酸酯物和光源扩散器，露出装于其内的LED灯泡。当有人坐在跷跷板的两端，并抓住中间的金属手柄时，该装置就会被激活。其中有若干跷跷板的良多各有两个把手，特意让多人同时使用。当跷跷板的一侧接触地面时，装置内的灯会被接通并透过透明的外壳发光。当没人使用时，装置会平衡与水平位置，并维持较低的亮度。
Each seesaw features a clear polycarbonate covering and light diffuser that reveals the LED bulbs inserted inside. To activate the installation a person mounts each end and grabs hold of the metal handle. Several of the seesaws have two handlebars on each end allowing several people to use the ride simultaneously. When one side touches the ground, the lights are switched on and shine through the transparent covering. When not in use, they stabilise, balance horizontally and emit a dim glow.

当跷跷板上下变化时，安置于内的扬声器将播放各式各样的音乐。装置的音量随机，并始终保持相互不同。Garment区联盟补充道：“跷跷板不断变化，构成了动态的光感和声带，激活并点亮了区内的百老汇行人广场。”
脉冲装置由Lateral工作室,设计机构CS Design及结构工程师EGP Group合作完成。装置内的音乐由声音设计师Mitchell Akiyama和电子设计工作室Robocut创作，并由Generique Design制作完成。该作品于2015年蒙特利尔的光疗（Luminothérapie）艺术节上首次演出。

Speakers wired inside each individual seesaw play the variety of musical sounds as the piece moves up and down. The noises are randomised and create a composition that is always different. “The ever-changing composition creates a dynamic light and sound wave, animating and brightening the Garment District’s Broadway pedestrian plazas,” the Garment District Alliance added.
Lateral Office collaborated with design agency CS Design and structural engineers EGP Group to complete Impulse. The musical score was created with sound designer Mitchell Akiyama and electronic design studio Robocut, while fabrication was completed by Generique Design. The work was first presented in 2015 at Luminothérapie, a festival in Montreal.
脉冲装置将在纽约市区服务至2020年1月31日。Garment区联盟与纽约市交通运输部（DOT）所倡导的艺术计划（Art Program）及公共空间街区季节性项目（Public Space Unit’s Seasonal Streets programme）合作。脉冲是该区域广场上艺术装置的一部分。目前，纽约市内类似的项目还有由Hou de Sousa完成的Ziggy及一个发光的游泳池，前者呈现为一系列缠绕有鲜亮绳索的钢筋框架，后者漂浮在East River上，旨在测试并监控河水水质。
Impulse is installed in New York City’s Garment District until 31 January 2020. The Garment District Alliance collaborated with NYC DOT’s Art Program and the Public Space Unit’s Seasonal Streets programme to create the installation as part of Garment District Art on the Plazas. Other recent installations in New York City include Ziggy, a series of rebar frames covered in bright cords by Hou de Sousa and an illuminated swimming pool that floats in the East River to test and report on water quality.
