*l.o* (pronounced el-dot-oh) is a series of audiovisual vignettes exploring a process at the heart of generative art and ambient music: creating complex forms by repeating and transforming a simple input. Inspired by starling murmurations, the repetition of a line, dot, or ring forms a flock of flickering particles rippling across the canvas. Interconnected audio and visual patterns create a mesmerizing display of echoes and modulations. As the sound expands and contracts, so do the areas of visual density, revealing ephemeral shapes and structures. Sounds become visible. Visuals become audible.

Within the sonic component, filters and echoes manipulate a sustained chord until subtle melodies and rhythmic structures appear, resulting in a hypnotic and evolving soundscape unfolding from an elementary source. The signal path relies solely on bespoke code built using Web Audio, including an implementation of an early computer music algorithm called *Karplus-Strong* which utilizes tuned delay lines to simulate the physics of stringed instruments. The audio effect design is also inspired by the magical warmth of vintage analog equipment like tape loop echo units. This analog quality found its way into the visual style: the low frame rate gives the project a hand animated feel reminiscent of stop motion.

On our last album, [Still](https://silentseason.bandcamp.com/album/still), we questioned the repetitive experience of pedestrian life, attempting to invoke wonder in the constantly evolving nature of our world, even in moments of perceived stillness. *l.o* expands this line of inquiry, inviting the audience to appreciate the compounding complexity surfacing from a succession of small shifts within a fixed pattern. As the series builds, various directions of color, shape, tone and tempo are unveiled.

Alongside works like *Flux* by Owen Moore, or *montreal friend scale* by Amon Tobin, the project explores core questions about the audiovisual medium: can it be more than visuals in the service of sound, or sound in the service of visuals? How can the synthesis of the two media create a richer whole? While the sound of *Flux* reacts to visual data, and *montreal friend scale* is a literal visual representation of a sonic concept, *l.o* features a two-way dialogue between sound and visuals. The two are interconnected through 9 different paths, including a key relationship where filter frequency modulates flock density (more details available in the [AV section](https://l.o.night-sea.com/#av) of the project’s website). This audiovisual conversation offers a unique encounter between generative visual art and abstract electronic music, two vibrant spaces that share a common thread.

Key controls are available to explore the different components building the final sound:

- Press ‘0’ to turn off all effects and hear the initial sustained chord
- Press ‘1’ to toggle back on / off the amplitude modulation (can sound subtle in certain outputs)
- Press ‘2’ to toggle back on / off the filtering effects
- Press ‘3’ to toggle back on / off the echo based effects
- Press ‘Space’ to pause / resume the piece

After pressing ‘0’, pressing successively ‘1’, ‘2’ and ‘3’ will bring the piece back to the original audio setup.

Established in November 2022 as a successor to the Playground and Factory collections, Art Blocks Presents featured generative art projects that were selected by the Art Blocks team and complemented the Curated collection. The Presents collection embodied our ongoing standards for artistic creativity, conceptual rigor, and technical achievement.
