This paper details the design and development of a novel musical controller. Inspired by a type of Synesthesia where colour typically induces musical notes, MusiCam explores the potential benefits of this idiosyncrasy as a mode of Human Computer Interaction (HCI), providing a host of meaningful applications. Colour data is interpreted by means of an off the shelf webcam, and music is generated in real-time through regular speakers. This simple design flexibility allows for any personal computer to take on the identity of an interactive musical device.
