Artist Jim Sanborn’s sculpture Kryptos Is included here because the text inscribed on it has created a mystery that even the best code-breakers in the CIA have not been able to unravel. The sculpture was commissioned by the CIA as a monument to the intelligence gathering work that made the agency famous, and it was installed at their headquarters in Langley, VA in 1990. Sanborne collaborated with a top CIA cryptographer to create a complex "riddle within a riddle".
In May 2007, a huge lake in Chile literally disappeared overnight. The only things left behind was a giant, 30 meter deep pit, icebergs, and dry soil! All of the water and its contents were gone. Despite the fact this strange incident took place more than two years ago, word is just now getting out about it.
