Dilating Sky

Dilating Sky connects human interaction with cosmological history through meteorites as physical interfaces. By repositioning these extraterrestrial fragments, visitors translate ancient impact events into immediate sound and light. The work creates a direct link between bodily gesture and astronomical data, compressing eons into tactile experience. Meteorites function as both historical records and playable instruments, allowing participants to access temporal scales beyond ordinary perception. The installation transforms passive observation into active engagement with cosmic material, enabling a form of time travel where deep history becomes present through touch.

Dilating Sky uses meteorites as controllers for an interactive sound installation. A wooden table with an embedded magnetometer detects the magnetic fields of meteorites placed on its surface, triggering a step sequencer that plays a sampled lithophone. A motorized aperture above the table autonomously opens and closes, casting a fluctuating circle of light below. As the aperture dilates, it plays an expanding dataset of music composed from meteorite impact data. Visitors manipulate the meteorites on the table to play along with this cosmic score, creating a duet between human gesture and astronomical information encoded in cosmic materials and data-driven sound.
