Declination Cruft

This cruft algorithm extracts images from the Fox News home page once every eight hours. The headline and story text is parsed, and an image from this page is then manipulated into a dense blending of text and image. Viewing the archive one can see the limited range of changing news stories, seeing clearly where Fox News wants us to focus our thinking. Just like the magician's misdirection, we focus on one hand, so we are no longer thinking about what the other hand is doing.

Magnetic Declination
Magnetic declination or variation is the angle on the horizontal plane between magnetic north (the direction the north end of a compass needle points, corresponding to the direction of the Earth's magnetic field lines) and true north (the direction along a meridian towards the geographic North Pole). This angle varies depending on position on the Earth's surface, and changes over time.

The magnetic declination in a given area may (most likely will) change slowly over time, possibly as little as 2–2.5 degrees every hundred years or so, depending upon how far from the magnetic poles it is. For a location closer to the pole like Ivujivik, the declination may change by 1 degree every three years. This may be insignificant to most travellers, but can be important if using magnetic bearings from old charts or metes (directions) in old deeds for locating places with any precision.
