: This paper presents Musimage, a novel system which displays pictures according to the songs being played at the same time. By using the interface the user selects the songs to be played, but the pictures are automatically selected. For each song to be played, the system selects a set of pictures, according to various criteria corresponding to some features of the song. In this sense, the pictures to be shown are, metaphorically, triggered by the songs. Key Words: intelligent user interface, indirection of information, ambient intelligence
