The Eyeborg

Rob Spence, a Toronto-based film-maker, lost his right eye in a shooting accident on his grandfather's farm when he was a teenager. Now 36, he decided some years ago to build a miniature camera that could be fitted inside his false eye. A prototype was completed last year, and was named by Time magazine as one of the best inventions of 2009. He calls himself "the Eyeborg guy".

The eye contains a wireless video camera that runs on a tiny three-volt battery. It is not connected to his brain, and has not restored his vision. Instead it records everything that he sees. More than that, it contains a wireless transmitter, which allows him to transmit what he is seeing in real time to a computer.
The current model is low resolution, and the transmitter is weak, meaning that Mr Spence has to hold a receiving antenna to his cheek to get a full signal. But a new higher-resolution model, complete with stronger transmitter and a booster on the receiver, is being built. He says: "Unlike you humans, I can continue to upgrade." Mr Spence also has a version with a red LED light in the eye, like the robot from the Terminator films.
The eye was built with the help of Steve Mann, a professor at the Massachusetts Institute of Technology and an expert in "cyborg" technology - the blending of natural and artificial systems with technology.

King Coin

A Spanish precious metals trading company bought the world's largest gold coin for 3.27 million euros, its exact material worth, from the estate of an insolvent investment firm at a rare auction in Vienna on Friday.

The 100 kg (220.5 lb) piece, one of only five Canadian $1,000,000 Maple Leaf coins the Royal Canadian Mint has ever produced, was snapped up immediately in a written bid from ORO direct, a gold trading company based in Madrid.

The auction was ordered by the administrator of Austrian investment group AvW Invest, which filed for insolvency in May after its owner and chief executive was arrested on suspicion of fraud, breach of trust and other charges.
AvW had acquired the coin in 2007, joining an exclusive club of owners including Queen Elizabeth, who is also displayed on one side of the coin, two unidentified investors in Dubai and one who is so reclusive even his or her residence is unknown.
AvW had lent its coin, 53 cm (21 inches) in diameter and 3 cm thick, to Vienna's Kunsthistorisches Museum where it had been on display as part of its coin collection.
Its purity is 99.999 percent, the purest type in the market.
bi The Royal Canadian Mint launched the coin in 2007 to showcase its production facilities and steal the entry in the Guinness Book of Records for the world's biggest gold coin.
