Writing in sand visible from space
Hamad bin Hamdan al Nahyan, a billionaire Sheikh and member of Abu Dhabi's ruling family, has had his name carved into the sandy surface of an island he owns in the Persian Gulf. It is no lackadaisical sand-scrawling, though: At half a mile tall and 2 miles long altogether, the letters HAMAD are visible from space.
Satellites captured these images of al Futaisi Island, stamped with the name of its owner, back in 2009. They can be accessed on Google Maps and Google Earth.
While, under normal circumstances, words written in sand wash away, The Daily Mail explains that these letters are large enough to "form waterways that absorb the encroaching tide." Indeed, at the time the satellite photographs were taken, said tide can be seen flowing through the letters all the way to the M.
