In the video, Matt Busch, the map artist, discusses the genesis of the map from a sketch, and how he symbolized the map, created the detailed legends, and added the basemap context to the map. It's pretty nicely organized. And he was fairly fanatical about the research that went into it, as evidenced by his copious notes and charts. I nominate Matt to the Legion of Honorary Cartographers for this effort.

One of the reasons the concept of Flâneur-ism is typically associated with men is that until quite recently women did not have the ability to wander safely and unaccompanied and anonymously through the city, and go wherever they pleased. Many areas were off-limits to women, for one reason or another. Therefore, le Flâneur was almost always a male, since being able to move through the city anonymously and without attracting undue attention is one of the pre-requisites, in fact it is the hallmark, of Flâneur-ity. It is also the reason why, throughout time, certain bold women have decided to masquerade as men, to have access to that type of urban observer anonymity and jettison all the restrictions that normally devolved upon their gender.

This is the link to an excellent Interactive Map showing conflict events in Libya from February 20, 2011-August 15, 2011. (Thanks for sending the link, Suman Basyal)
Here is a rather depressing and sobering pie graph, based on a survey taken in June, 2011.

Above, left: cylindrical "normal": Above right: cylindrical transverse; lower left: cylindrical oblique.
Then, to complicate matters even further, the "developable surface" can be "tangent," considered to have points or lines of tangency where it is touching the globe, or it can be "secant," which means the developable surface seems to be slicing through the globe. Secant projects have the advantage of additional points of tangency, and therefore more areas on the map that are "true."
And, then, we have projection classification by method of light source: from where, in our imaginary transfer of data from the face of the globe to the projection surface, is the light coming? There’s Gnomonic (light projected from the center of the globe to projection surface); Stereographic (light projected from the antipode of point of tangency); or Orthographic (light projected from infinity).
And, here are some tres cool maps that use unusual projections which I found when poking around on the Internet:
This is a map of Human Migration, using the Dymaxion Projection. The choice of this particular projection highlights the interconnectedness of the land masses of the world, and makes it easy to see the flow of humankind over the centuries.
Another one based on the Dymaxion Projection! and I suspect for the same reason as the Human Migration map. This one portrays a prediction of the energy grid of the future, with various types of energy sources named.
And, just for kicks, here is the Cassini Projection, developed by César-François Cassini de Thury in 1745. This is the son of the guy for whom the Cassini spacecraft was named (Giovani-Domenico Cassini), even though NASA is not using his projection to map the data, but rather an oblique conformal projection. But Cassini (the elder) was the first to observe and document Saturn’s moons, and that’s probably why they named the spacecraft after him. He also began the work to create a comprehensive topographic map of France, work that was completed by his son and grandson over a century later. He used the then-new method of triangulation and his own method of determining longitude, which meant that this was the first truly accurate map of France. Unfortunately, this accuracy resulted in a much smaller France than the Sun King Louis XIV (who commissioned the survey) was expecting. Apparently the King joked that Cassini had taken more of France from him than he had won in all his wars. It was the first topo map of an entire country.
An application of theCassini Projection - Present and fossil teeth suggest several migration waves in the past, when reduced sea levels created bridges between now isolated Japanese and Aleutian islands. From:
And to end up on a humorous note, here is a part of a poem about, of all things, maps! and their use (or not!) in navigation

And, the last word!
The Bible Map of the World, 1893, by “Professor” Orlando Ferguson of Hot Springs, South Dakota, a geocentrist who created the map based on 400 passages in the Bible that supposedly describe what the Earth is like, and none of them supports the idea of a spherical earth, or one that revolves around the Sun. Apparently, according to a 1996 Gallup poll, about 18% of Americans agree and believe the Sun revolves around the Earth.
