Hi guys -
What facscinates me with Google Earth is being able to 'zoom in' on complex geographical features, eg deserts, rivers, mountains, etc.
You really get to see the 'FRACTAL GEOMETRY' of nature (Thanks Mr. Mandelbrot). 😎
Check out the mountain ranges and deserts of the Yemen, for example - If you zoom in here you will see a striking network of dunes, valleys and ranges that resembles branches of trees, arteries in the human body, and ofcourse Benoit Mandelbrot's 'set' - an abstract mathematical construct, but one which mimics nature perfectly.
