Looks Like Music
This is a lovely project by Mudam Gallery in Luxembourg, combining art and music and technology into a rather beautifully whimsical piece of work. To quote them, 'For its summer project, Mudam’s Publics Department invited the Japanese creator Yuri Suzuki to conceive Looks Like Music, an audiovisual installation based on his work Colour Chaser. This consists of a miniature robot which detects and follows a circuit – a black line traced in marker pen – interspersed with coloured reference points that the device translates in sound. The public is invited to actively contribute to the development of the installation in the exhibition space by extending the circuit drawn on paper. Visitors thus participate in the creation of a large-scale artwork and enrich a collectively composed sound piece'.
We suggest you watch the video, though, as it's better than any prose explanation:
