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.
Spatial Interfaces
Software applications can utilize spatial interfaces to afford users powerful ways of thinking and interacting. Though often associated with gaming, spatial interfaces can be useful in any kind of software, even in less obvious domains like productivity tools or work applications. We will see spatial interfaces move into all verticals, starting with game-like interfaces for all kinds of social use-cases.
There is no app that replicates a deck of cards
It seems that the only way to build an app that replicates the full functionality a deck of cards is to build a 3D simulation or game. Model the cards in 3D and put them on a 3D table. As long as you have controls for reaching out and picking up the cards, and moving them in space, you can do anything you can do in real life.
Preserving the higher dimensionality makes it simpler and more intuitive, not less.
Humans are spatial creatures
Humans are spatial creatures. We experience most of life in relation to space. We sit in a circle with our family. We drive down the left side of the road in Ireland and try to stay in our lane. We ride scooters down a path along the water. We sculpt a human body out of stone. We follow signs to our train. We walk, through arches, or on crosswalks beside bike lanes, or to follow our brother across a bridge. We position our camera to frame the shot while our friend leans out over a balcony. We sense ourselves in space in relation to all of the other objects in our environment.
And this is powerful knowledge that we've left out of lots of software. In fact, while most obvious in 3D, this thinking does work outside of just three-dimensional software. Almost any software can use spatial concepts to become easier to understand.
Web trails
There's more room for spatial concepts to become part of our web browsing experience.
One example is an idea I call "trails." It's based on the story of Hansel and Gretel walking through the forest and leaving a trail of breadcrumbs behind them, so that they could find their way back later. What if you could do this on the web?
A breadcrumb in this case is a single pixel that you can place in a precise location on a webpage. Placing a breadcrumb could be as simple as Option + click. While navigating the web, you could leave breadcrumbs on different pages you find interesting over the course of a browsing session. When you're done, that sequential "trail of breadcrumbs" would be saved. You could then jump back into the trail and navigate "forward" and "backward" through the things you found interesting in that browsing session. Or share the trail with a friend, and they could step through your spatial path of navigating the web.
