The amazing Dice sculptures of Tony Cragg
From a distance, it’s difficult to tell that these abstract sculptures are even more impressive than they first appear. As viewers near each piece, it quickly becomes evident that the large, organic shapes are completely covered with dice. In the collection, Germany-based artist Anthony Cragg used only small, black and white cubes to construct the surface of each unique form. He did not find himself limited to the hard, square edges, and used thousands of the objects to create a variety of mesmerizing curves that mimic nature. ( Quote from mymodernmet.com )

Tor, an acronym for “the onion router,” is software that provides the closest thing to anonymity on the Internet. Engineered by the Tor Project, a nonprofit group, and offered free of charge, Tor has been adopted by both agitators for liberty and criminals. It sends chat messages, Google (GOOG) searches, purchase orders, or e-mails on a winding path through multiple computers, concealing activities as the layers of an onion cover its core, encrypting the source at each step to hide where one is and where one wants to go. Some 5,000 computers around the world, volunteered by their owners, serve as potential hop points in the path, obscuring requests for a new page or chat. Tor Project calls these points relays.
Numbers stations are mysterious shortwave radio channels of indiscernible origin that exist in countries all across the world and have been reported since World War 1. They are identifiable by the unusual contents of their broadcasts: seemingly random sequences of numbers, words, letters, tunes, and Morse code, usually spoken by artificially generated voices of women and children.
The most common theory regarding the purpose of these bizarre stations is that they’re used by governments the world over to secretly transmit encrypted commands and messages to spies. That said, even though numbers stations have been discovered all over the globe and in any number of different languages, no government has ever officially acknowledged their existence. While the espionage theory is a logical one, with no official confirmation of their purpose the jury is still out.
One particularly odd station, UVB-76, has existed since the late 1970s and has broadcast a simple, repetitive buzzing tone 24 hours a day ever since. On very rare occasions, however, listeners have reported a Russian voice interrupting the buzz to read out sequences of numbers and words, always in a consistent format — this happened once in 1997, once in 2002, once in 2006, 56 times in 2010, and 14 in 2011. As with all numbers stations, its true purpose is and will probably remain unknown, but the increase in frequency of whatever it’s doing is certainly odd.
You can listen to well over 100 recordings of numbers stations for free on archive.org but be forewarned that they’re all kind of, well, eerie. They feel like something you shouldn’t be listening to, which stands to reason since apparently you’re not supposed to know they exist.
The Swedish Rhapsody is easily the most disturbing of these. It plays what sounds like ice cream truck music, and a little girl says the numbers…
