Cover Art : An acoustical capacity meter and an engine

The volume of the space inside the engine, which can’t be viewed from the outside, is revealed by sound. This device can instantly quantify the volume even of objects with complex shapes. In this artwork, hard metal components are shown with colorful, intermingled structural parts to express the relationship between the machine and measuring device. The cable extending from the measuring device resembles a stethoscope placed to attend to the heartbeat of the engine. This work captures the moment at which the invisible world is made visible by sound.
