"jumping jack" is a single-channel micro media piece that plays a found youtube video of two people using a Belle RT Trench Rammer. the tool is used to provide a high-impact force to compress material. the sound is super violent and if you live in a city you know the sound. i thought it would be fun to have such a loud and powerful machine relinquished to such a small display. it has been displayed with both loudspeakers for a booming effect, as well as with headphones, giving a more personal experience with the noise of a trench compactor.
