Technique: you receive an email from a friend. The email includes a link to an online movie.

In the movie, you see all kinds of people phoning each other. In the final sequence, a guy dials a number and at that moment, your mobile phone actually rings. When you pick up the phone, a mysterious voice tells you that 'Beguinage' is the password to win two MINI for the summer. It really seems as if the guy in the phone booth is talking to you!

(the actual phone call is no longer active)
