A reconstructed version of the world's oldest computer has been unveiled in Greece.

The 2,000-year-old device was found by chance on the ocean floor more than a century ago.

Michael Wright, a former senior curator at London's Science Museum, unveiled the complex collection of gears and dials at a conference on ancient Greek inventions.

Experts attending the symposium praised the model as the best yet of a device that is believed to have calculated the motions of the sun, moon and planets.

Mr Wright said the shoe-sized box object not only illustrated the ancient Greeks' love for gadgets but how advanced they were technologically.
