To promote the service of a cab company, in bars and clubs. The message they wanted to communicate was have fun but keep in mind the dangers of drunk driving. Making sure that their communication has no impact on liquor sales of the barclub was another challenge. The solution was the “magic mirror” wich hung in rest rooms. It like any ordinary mirror but transformed its image when a person went closer to it. The picture of a person who has met with an accident would appear with the message “take a cab” and the contact number of the cab company.

What a clever design, but how did they do it?
