Avantura linije (Adventure of the Line) is a book of original drawings used to make the trailer for the World Festival of Animated Film in Zagreb in 2002, but also an unusual animation textbook / instructions guide for those interested in the medium. All drawings (altogether 699) were published in a series, as they appear in the film, together with storyboards.
Only by knowing Dragić's previous work can one assess the mastery of the work conducted on the Animafest trailer. After Dragić's initial signature, the black background merges into a black stretch carried close-up by a bird, while the background turns to white. What we see is, in fact, an illusion. The bird consists of lines, which form shapes, which are again dissolved. Abstract is concrete, and things seamlessly become something else. In order to closely watch their changes, the only thing you can do is to delve into the series of drawings in this book on watch the accompanying DVD at the slowest possible speed, frame by frame.
