Escher Effect at Empire State Building
Here's another example of the "Escher Effect" that's sometimes seen in satellite pictures. This pic was screen-grabbed from Google Maps.
The effect is caused when two separate airplane or satellite pics are taken of different sections/plots of a city, and then stitched together. Each pic is taken from a different angle, so the taller buildings' pics are taken with different perspective points, causing them to appear to lean toward or away from each other.
See my other Escher Effect Pics.
Also, view the original Google Map of the Empire State Building.
This photo is Geotagged, too! To view a map of the location from within Flickr along with many other people's photos of the building, click on the (map) link in the lower right-hand column.
UPDATE 4/18/2010: Google Has Fixed The Escher Effect.
