Once upon a time I was a young teaching assistant teaching Aerial Photography Interpretation, and one of the aspects that I found difficult to demonstrate was Parallax, the displacement of high features such as towers in photographs. You will see this today when looking at some of the images in Google Earth which have not been corrected to remove the resulting building lean.
Now as a result of the technological marvel thats is WebGL you can seen Parallax demonstrated dynamically in Google Maps, just one of the ways online maps are moving beyond the static paradigm of traditional cartography.
