Escheresque photorealistic compositions in GMaps

When I was browsing Google maps I found this image of Houston. It looks a bit like an Escher image. The perspective of some of the buildings is completely out of context, notice the difference between left and right of the image. Somehow some stichting software, a photoshop enthousiast or a wicked lens has perfectly connected the different perspectives into one image.

Or what about this image?
