2 different ways to change the drag on a plane?

Is there any software that will dynamically re-project a map as you click-and-drag it?

• Is there any software that will dynamically re-project a map as you click-and-drag it? Is there any existing software that will let you click and drag the map and show you a new projection as you change the focus (what falls in the center) of the map? (The map would use http://en.wikipedia.org/wiki/Wraparound_%28video_games%29--whatever goes "offscreen" on one side immediately appears on the other side, north-south and east-west). It would be cool to do this with projections other than the Mercator, too. I'd like to see a map where e.g. Mexico is distorted the way Greenland usually is. Something that could distort the globe dynamically. A dynamically distorted map would make it easier for students to understand how maps show you the world as if through a fisheye lens. Is there such a thing? If not, what would it take to write a program that could do this? I was on a long plane ride earlier this year staring at the flight path map and I got to thinking about globe projections and how distorted they are. The most popular globe projection, the Mercator map, distorts Greenland into a huge landmass comparable to Africa. Everything is distorted. It's like looking through a lens that warps the size and shape of everything, especially around the edges. All map projections do this to some extent. (I was also going to ask what it would take to photograph a person's head from all sides and project it to a flat surface, to use it as another tool to emphasize how badly flattening distorts a round object, but then I realized that http://www.testroete.com/index.php?location=head (the big-head Halloween costume guy) http://www.testroete.com/personal/head/texture.jpg)
