Hertzian Landscapes
Hertzian Landscapes (2019) is a live visualization of the radio spectrum. Unlike visible light, waves in the radio spectrum cannot be perceived by us directly yet this space is teeming with human activity. Hertzian Landscapes employs a digital receiver to scan large swaths of radio spectrum in near real-time and visualizes thousands of signals into a panoramic electromagnetic landscape. Users can zoom in to specific frequencies by positioning themselves in front of the panorama as if controlling a radio tuner with their body, giving them a sense of walking through the spectrum.

Particle Waves
“Particle Waves” is a kinetic sound sculpture comprising of a 4×3 grid of 12 individual kinetic bowls. Within each bowl contains tiny metal beads of various sizes, creating noises as the bowl rotates in various angles. The noise from a single bowl forms collectively to become a soundscape, reminding us of waves and oceans. The bowls are arranged in a 4×3 grid and controlled as a whole by a microcontroller running a wave algorithm. This creates a continuous wave-like kinetic motion over the grid, at the same time creating a spatialized soundscape. This installation is a continuous attempt of exploring the correlation between sound and nature.


the shape of sound

80 mesh – the shape of sound’ is a project that investigates fragmentation, reconstruction and repetition generated through the morphogenetic
possibilities of sound waves – visualized through the modeling of fine grain sand. the work was curated by ravenna-based cultural association
marte and born from a collaboration under the artists group CaCO3 – coordinated by daniele torcellini. the multidisciplinary artwork – informed by the research of the german physicist ernst chladni – is a device composed of three 50 x 50 cm metallic plates that are placed horizontally alongside each other, with a quantity of garnet sand (80 mesh references the particles size) homogeneously dispersed over the plates. the dishes were electrically linked to the sound waves produced by an onde martenot – an early electronic musical instrument invented in 1928 with a similar sound to a theremin – played by ratsimandresy.
