架构师提供的文本描述。该项目一开始就有兴趣挑战停车结构作为一种不受重视的基础设施类型的典型概念，将新的Eskenazi医院停车结构转变为一个二元的、综合的地形。一个由7，000个角度的金属面板组成的区域的效果，再加上一个铰接式的东西颜色策略，创造了一个动态的外观系统，根据观测者的有利位置和他们在现场移动的速度，为他们提供了独特的视觉体验。这样，在靠近医院的地方，行人和缓慢行驶的车辆在穿过医院场地时，会在颜色和透明度方面出现明显的、斑驳的变化，而驾车沿着W.密歇根街行驶的人将经历更快、更梯度的颜色变化，这种变化取决于他们的旅行方向。

Text description provided by the architects. This project began with an interest in challenging the typical notion of the parking structure as an unappreciated infrastructural typology by transforming the new Eskenazi Hospital parking structure into a binary, synthetic terrain. The effect of a field of 7,000 angled metal panels in conjunction with an articulated east/west color strategy creates a dynamic façade system that offers observers a unique visual experience depending on their vantage point and the pace at which they are moving through the site. In this way, pedestrians and slow moving vehicles within close proximity to the hospital will experience a noticeable, dappled shift in color and transparency as they move across the hospital grounds, while motorists driving along W. Michigan Street will experience a faster, gradient color shift which changes depending on their direction of travel.

该项目旨在探索二维图像构建技术与建筑围护结构设计和制造中的构造考虑之间的相似之处。通过对数字图像处理和再现技术的严格研究，如误差扩散、抖动、半色调和有损压缩量化等，提出了一种在建筑立面上表达图案和边缘复杂排列的策略。

This project sought to explore parallels between techniques of two-dimensional image construction and the tectonic considerations present in the design and fabrication of building enclosure. Through rigorous examination of digital image manipulation and reproduction techniques, such as error diffusion, dithering, half-toning, and lossy-compression quantization a strategy for the articulation of complex arrangements of patterns and edges across a building façade was developed.

我们的工作室在2012年8月被委托设计并实施制造和安装。我们开发了这个概念，最初是源于主动伪装技术，然后通过设计开发图纸。在这个阶段，材料和结构方面的考虑被考虑了。我找到了一个当地的制作者，负责这个项目的实际制作和安装，然后在2014年5月安装。

Our studio was commissioned to design and then implement the fabrication and installation in August, 2012.  We developed the concept, which began initially as an idea stemming from active camouflage techniques,  and then worked through the design development drawings.  During that phase, material and structural considerations were worked though, and I located a local fabricator that handled the actual fabrication and installation of the project.  It was then installed in May, 2014. 

伪装最初在概念上是很有趣的，因为立面的主要目的是为原本普通的停车结构提供一个密集的视觉屏幕。随着项目的推进，人们对伪装的兴趣逐渐演变成一种方法，为城市创造了一个非常大的动态、互动元素。而不是一种积极的动力方式。随着所有不可避免的维护和长寿的关切，伴随着这些类型的项目，我们转而致力于一种方法，利用这样的事实，大多数观众将移动，他们自己.无论是步行、骑自行车，还是在汽车里。因此，这种设计最终成为了某种程度的东西，当你经过这个项目时，它提供了一定程度的颜色和形式的变化。有趣的是，不管有人是直接观看还是仅仅是从他们的视觉边缘看到它，人们都会意识到这一点。

Camouflage was conceptually interesting initially, as the main purpose of the facade was to provide an intense visual screen for what is otherwise an ordinary parking structure.  As the project progressed, the interest in camouflage evolved into an approach that would create a very large dynamic, interactive element for the City.  Rather than an actively kinetic approach, with all of the inevitable maintenance and longevity concerns that accompany those types of project, we were instead working towards an approach that capitalizes on the fact that most viewers would be moving, themselves... either walking, biking, or in an automobile.  Thus, the design ultimately became something that offers a degree a variability of color and form as one passes by the project.  The awareness of this, interestingly enough, occurs whether someone is directly watching or even just seeing it out of their periphery of vision.

我们在工作室里做了大约6个月的物理模拟，就像你想象的那样，软件变得非常重要，我们甚至不得不自己编写一些软件来帮助我们创造最终的效果。

We worked on the design and built physical mock-ups in our studio for about 6 months.  As you might imagine, software became hugely important, and we even had to write some software on our own to helps us create the final effect.

为了达到这一效果，一共使用了18个不同的面板大小/角度，从300毫米高x 600毫米长到300毫米长x 1米长。这些面板大约有7000块。配色方案很简单，因为西侧的颜色是深蓝色的，而东侧的颜色是金色的。光是角度，就可以了。创造不同颜色的错觉。

To facilitate the effect, a total of 18 different panels sizes/angles are used throughout.  They range from 300mm tall x 600mm long to 300mm  tall x 1m long.  There approximately 7,000 of these panels.  The color scheme is quite simple as the west side received a deep blue color, while the east side receives a golden yellow color.  The angles, alone, create the illusion of different hues.

这个项目主要是一件大型艺术品。其次，它当然是一个视觉屏幕，用于后面正常的停车场结构，掩盖人们可能看到的正常事物，比如汽车、混凝土梁、柱子、护栏等。它需要有大量的通风，这是一项要求，当然，这一概念与这一概念很好地结合起来了。

The project is primarily a large art piece.  Secondarily, it does of course serve as a visual screen for a normal parking structure behind, masking the normal things one might see such as cars, concrete beams, columns, guardrails, etc.  It was required that the piece allow for substantial ventilation, which as a requirement, naturally worked well with the concept anyway.
