 * One loudspeaker (new, second-hand or salvaged), or one old electronic device containing a functioning loudspeaker of decent size (approx 00mm or larger) which we can remove. The size of this loudspeaker will determine the tone and loudness of your instrument - bigger is usually better. Look in old radios, electronic clocks, hi-fi systems, boomboxes or car audio systems for your own unique speaker! * A cigar box or similar wooden box to create the instrument. The box should be big enough to hold your speaker, and the lid must not be thicker than 0mm. Alternately, I will have cigar boxes and loudspeakers for sale if you cannot locate your own. Participants may also wish to bring their own found objects and images to create a unique audiovisual cabinet of curiosities. Some guitar effect pedals can also make the box more interesting. All other materials and tools will be provided.
