Tracing Power Lines with the Pylon Appreciation Society
Pylons
Not all the towers along a transmission line are identical. Look closely at a tower where the line makes a sharp turn and you will likely find it is wider and beefier than other towers along the route. The added strength and weight are needed to resist the unbalanced pull of the conductors, which might overturn an ordinary tower. These special towers are called deviation or angle towers.
The transmission-line tower everybody knows is an Erector Set latticework of steel girders and diagonal braces. The techniques for designing and building these towers are the same ones used in constructing steel bridge trusses or crane booms. The individual pieces can be made cheaply from rolled steel and then bolted together on the site. This last point is more important than it might seem: transporting a fully assembled tower 100 feet tall is an awkward and expensive business.
A haunting, syncopated music
"Rappers" on the roof of the electrostatic precipitator knock the accumulated dust free, letting it fall into the storage hopper. Each rapper is the size and shape of a baseball bat. Inside is an electromagnet that pulls a steel plunger upward, then allows it to fall again, producing a sharp knock. The rappers are energized at seemingly random intervals, producing a haunting, syncopated music. (The rhythm seemed more modern jazz than rap.)
Safety cut rope axe man
In the first nuclear reactor, constructed by Enrico Fermi in 1942 under the bleachers of the University of Chicago football stadium, the control rods were held up by a manila rope. A man with an axe was told to cut the rope if the reactor got out of hand. This "safety cut rope axe man" is supposedly the origin of the term SCRAM for an emergency shutdown procedure.
Color coding
Telephone wires erupt in a multicolor cascade in a ground-level, pedestal-type splice case on a city street.
Dividing the set of 10 colors into two contrasting groups of 5 allows for exactly 25 combinations with one color from each group; thus, each pair in a bundle can be uniquely colored. A similar color code is applied to the ribbons that bind together all the pairs in a bundle, and to those of the superbundles. The result is highly festive! A specific wire might be identified as the blue-red conductor within the orange-black bundle within the brown-yellow superbundle.
Phenomenal: Exhibited Works
Untitled (Light Canvas)
A key transitional work for Wheeler is his untitled "light canvas" from 1965. The canvas was primed white, then over-sprayed..., but with no emblems or polished elements. The contrast in the light canvas is provided not by any imagery within the painting but by back-lighting; the canvas is backlit with neon light, which is embedded in a reverse bevel Plexiglass frame that projects the piece about five inches from the wall. The effect suggests an eclipse, or some other spectral occlusion of a bright light source.

Stuck Red
Zero Mass
On an autumn night in 2009, I experienced a version of this piece installed in a stone barn in rural France. The evening was moonless and cold; I stood with two friends inside the piece for the better part of an hour, as our eyes adjusted to almost total darkness, before any of us could begin to see one another. It was the definition of a liminal, or barely perceptible, experience. Eric Orr, who died in 1998, was involved with Zen Buddhism and considered these pieces to be spaces for meditation. Experiencing them as intended requires the visitor to focus quietly on the mechanics of their own perception.
Little Blank Riding Hood
As a student at Chouinard, Larry Bell also started as a painter. His early canvases features simple shapes rendered in gestural strokes...From there he started eliminating the texture of the strokes, applying opaque color (thin Liquitex paint) to unprimed canvas, masking off shapes to create straight-edged parallelograms. An example of these works is Little Blank Riding Hood, whose top left and bottom right corners are clipped, suggesting an isometric projection of a three-dimensional form.

Untitled (White Light Grid Series-H)
The entire box is suspended from the ceiling by only four evenly spaced monofilaments, so that it seems to float with no physical connection to the wall or to a power source. Behind the wall (which must be purpose-built and is quite thin) is a cabinet containing four Tesla coils. The coils emit a high-frequency energy that passes through the wall and lights the tubes. The energy pulses a bit, making the tubes flicker at times both vertically and horizontally. The Tesla coils make a crackling static sound that is mostly muffled by the barrier wall, while the neon tubes emit a low hum that is audible close to the work. The work is elegant and slightly menacing, evoking something of a mad scientist's experiment.
Five Paintings IV
One of the most extraordinary examples of McCracken's illusory surfaces occurs with Five Paintings IV, 1974. This wall-mounted work has a black polyester resin finish. From some angles the surface is opaque, from others highly reflective, and from still others it seems to reveal great depth. A happy accident in the creation of the work sealed many tiny air bubbles or particulates in the piece. When these catch the light, they suggest a galaxy of stars on a moonless night.
