"A.I.": artificial Internet?

Most films have one official website. Steven Spielberg's science fiction tale "A.I. Artificial Intelligence" has dozens, and they have caught the imagination of Internet geeks like no other website has before.

Rather than build a typical promotional site, Spielberg's minions have built an online fantasy world within which exists a complex puzzle that echoes the movie.

Built into all the sites are clues that may help fans uncover the identity of a murderer. Somehow, this murder mystery is linked to the plot of "A.I."

Beyond the Web, the interactive game involves answerphone and text messages. Anyone who starts the journey into this mystery is pulled into the story and will find it difficult to stop playing.

Keen to solve the mystery, one group of cyber-gamesters has called itself . They refer to the makers of the game as the Puppet Masters, and to its mysterious, disembodied MC as Mother. They are deperately addicted. They love it.

The game is still there to play. All the details are at the Cloudmakers site. Be warned, though: once begun, the game is difficult to stop playing.

The Cloudmakers wondered from the start what they would get out of playing. When the film is released in the UK in September, will they have a better understanding of it than the rest of us? Early signs are that the game is only loosely connected to - and for some people, much better than - the movie.
