Located on a major intersection in El Paso, The work links the ballgame, a playground and the street. It provides the security of a partition, while facilitating coincidental encounters with the game from the sidewalk. It was fabricated from custom aluminum extrusions.

Individual extrusions were CNC milled with a wood grain pattern and anodized a warm copper hue. The grain pattern allows light to pass through the fence while the ribs diffuse the light.


Designers and Principals in Charge: Neal Feay Co Installation Consultant: Like the city itself, it does not have a distinct beginning or end; inside or outside; back or front.

It is both an object and an atmosphere. Its appearance is not static as it is predicated on changing quality of light in the north light well at any hour of the day. Air Garden is a serene moment amidst the hectic action and movement within the airport.

LAX is a city among cities that envelops the globe, networked through a system of concourses, gates, terminals and connecting flights; it is an international metropolis of movement. Air Garden is a pause within this movement; a place for reflection and repose, an opportunity for the traveler to daydream.

Its components are made of gestural volumes of color hovering within an immense array of catenaries. Our hope is that Air Garden procures a mental clearing for the voyager that is a respite from the pressures of travel and produce a felicitous condition for daydreaming. The work is like a cloud inside the light well, which can be clearly described using a term from chemistry: A suspension is a heterogeneous fluid or gas with solid particles more or less evenly dispersed within in it.

It is not opaque but more like a ubiquitous fog permeating the space. While the environment is interspersed with the metallic bead chain catenaries, it is also constructed from the negative space between the catenaries; sight extends into and throughout the building.

When developing the color composition of Air Garden we looked at the organization inherent in the architecture. We intend to shape color in three dimensions to echo the architectural order of the Bradley West Terminal by mimicking the shadows cast onto the array of catenaries by the structure members of the light well itself.

We chose two dates at which to cast the shadows, the summer solstice and the vernal equinox. To better understand the effectiveness of the hovering colored forms within the Air Garden we applied our findings from precursory research on theories of perception.

Testing in Gestalt psychology has proven that our mind puts together what is not explicitly present and imposes meaning and structure on visual input. These theories support our assumption that the traveler will mentally connect the architectural order of the building across the void of the light well by way of color painted onto the cloud of bead chain.

For this reason, we are able to achieve a visual connection without having to precisely replicate the geometry of the building but rather to imply its presence. The reflective qualities of the bead chain, that form the catenaries, create a sense of vastness through the play of light in space.

Each one is a miniature convex mirror, capturing light from all corners of the space as well as from the adjacent balls. The project evokes a sense of immensity through this reflective dance of color and light.

The consistent repetition of highlights on each bead produces a condition of being ensconced in a place that is both proximate and seemingly vast. Los Angeles is a region full of creative opportunity and innovation; Air Garden represents these characteristics.

Here, creative economies thrive. The real meets the unreal and Air Garden is a metaphor for this through its presence as both painted gesture and atmosphere. Air Garden embodies the sublime qualities of the utopian paradise we call home, Los Angeles. Ball-Nogues Studio Commissioning Agency: Ball-Nogues Studio Structural Engineer: The image alludes to a spiritual dimension of water, as well as its capacity to be both healing and foreboding.Mar 25,  · Crisscross method topic.

The Thorpe's Crisscross method is a method of finding out the chemical formula of a metal and non-metal that combine to form an ionic bond created by high school chemistry teacher Kim Thorpe. Following the crisscross method to write the formula for lead(IV) oxide would involve the following steps: The crisscross first yields Pb 2 O 4 for the formula, but that must be reduced to the lower ratio and PbO 2 is the correct formula.
