COMPLEX graffiti art featuring code-breakers and technological minds will appear across the country.

The murals, featuring mathematician Alan Turing, inventor Samuel Morse, Atari founder Nolan Bushnell, and Linux International executive director Jon Hall have been commissioned by Campus Party, a technology festival being held at London's O2 in September.

The coded graffiti uses Morse code, Java Script and Binary code, and the first set contains binary decimals.

The images will spring up in London, Birmingham and Bristol before the launch of Campus Party. Anyone able to break the code could win festival tickets.

An O2 spokesman said: "It is no surprise that Alan Turing should be the face to convey the first graffiti of the series given he is widely considered to be the father of computer science."
