How about some cool modified toy pianos
Five modified toy pianos circulate the gallery on five elevated wooden tracks. Each piano is equipped with small speakers to play amplified sounds picked up from conductive tape on the tracks. Each piano also contains small motors which intermittently spin to strike the toy pianos’ tone bars, adding acoustic elements to the overall soundtrack of the work. The installation also features five video monitors, which display images of five different real landscapes to compliment the abstract landscape of the wooden tracks. As the pianos begin to move around the gallery, these video landscapes are also populated by a seemingly infinite stream of mobile pianos. The video documentation composites footage of the installation in the gallery with footage shown on the monitors within the installation. This work was originally exhibited at the Museum of Contemporary Art, San Diego.
