由在马德里的Espadaysantacruz创意工作室设计制作，光动力是一组带有互动性质的光源装置，在这一装置中光的行为由一个物理模拟器控制。 
78个钨灯连接到一架4通道DMX调光器，装置由一个物理模拟器控制，该模拟器在Unity3D中编制。位于第一个灯泡内的压电式传感器捕捉着轻轻敲的力道，产生一个沿循环移动的光粒子。初始的脉冲根据轻敲的力度进行调节，创造出一个十分自然的互动过程。当碰触了力度较大时，光粒子的移动速度加快并且可以克服重力作用，当触碰的力度减弱是光粒子的移动速度变慢。
光，正如我们日常所见，是一种没有重量的元素，在重力法则的条件下来展现光的关系是非常奇妙的。这一装置所定义的光的行为是很难被理解的，因为他既没有表现为实体也没有表现为波动。正如爱因斯坦写的关于波粒子二相性：“我们有两种彼此矛盾的现象；他们不能单独解释光的种种现象，当时他们在一起时却可以”。在这个项目中，我们建立了一个计算机模拟器弱化了这一经典力学中的现象。
我们采用Arduino来捕捉敲击的动作并且通过Processing建立起Unity和调光器之间的界面。装置采用了20个DMX 调光器，压电传感器和oscP5同Unity和proDMX相衔接。
Created by Madrid based creative studio Espadaysantacruz, Light Kinetics is an interactive light installation where the behavior of light is controlled by a physics simulator.
Comprised of 78 tungsten bulbs connect to a rack of 4 channel DMX dimmers, the installation is controlled by a physics simulator built with Unity3D. A piezo electric sensor situated in the first bulb captures the force of a tap, generating a light particle that moves along the loop. The initial impulse is regulated by the strength of the tap, creating a very natural interaction. When one hits hard light moves fast and can overcome the force of gravity, when one hits the bulb softly light falls slowly along the loop.
Light, as we usually see it, is an element that lacks mass, to treat it under the laws of gravity is somehow magical. The laws that describe the behaviour of light are hardly understandable because it neither behaves as body or as a wave. As Einstein wrote concerning the wave-particle duality: “We have two contradictory pictures of reality; separately neither of them fully explains the phenomena of light, but together they do”. In this project, we have built a computer simulator that reduces this extraordinary phenomenon to the simple classical mechanical laws.
The team used Arduino to capture the impulse and Processing to interface between Unity and the dimmers. The installation uses 20 DMX 4ch dimmers, piezoelectric sensor, and oscP5 to interface with Unity and proDMX.
