This idea came up when I was bitching about the pictures condo developers show for their buildings. In Toronto, there is the CN Tower one of the tallest free standing structures in the world. Being so iconic most condo developers feel compelled to show the CN Tower even if they no where near. I mean if everyone can see the tower from everywhere, maybe we should just have long cable wires connecting major intersections, and everyone would just zip-line their way home and to work. Of course that would just mean a massive line up for the elevators at the CN Tower during rush hour.
All my lecture notes would eventually turn into something like this, back when I was in university.
