Overview
You look down and find that the ocean in your heart is a sine wave; the tide gently laps onto the shore. The soul is the sea, you are the land; there are waves on the shore, and the waves are slices. Gazing at the slices you feel the cold of the Arctic Ocean, the permafrost of the Antarctic sea, the deep darkness of the bottomless sea, and you hear the sound of waves lapping at innumerable shores far away. Feel the soul of the digital ocean.
I was in New York then, and out of loneliness I often took the subway to the sea and watched the waves break on the shore, as if in conversation with nature. In that moment a solitary cellist appeared in my mind, standing on the sand, looking out to the horizon, playing piece after piece to the ocean and the beach. SoulSea is my attempt to find out whether noise can carry the feeling I love most: the emptied mind of staring at an endless ocean washing in. The sea does not speak, and whatever mood or life story we bring to it, it does not judge; we keep proving ourselves inside the collective when all we are looking for is somewhere to belong, somewhere that ends the eternal loneliness.
Where the sea comes from
This sea has two sources. One is in New York: taking the subway to the shore out of loneliness, watching the waves break, imagining a cellist standing on the sand playing to the ocean. The other is on the desk: at the end of 2021 I wrote a wave for a commercial job, starting from a single wave and layering noise onto it in several places so the ripples ran continuous and natural, adding texture and small creatures, and it came out too beautiful to hand over, so I released it as my own. It was my second work on fxhash, two weeks after the first, SoulTree; the Chinese text of Soul Sea was conceived together with Mashbean.
On 29 December 2021 the work was published, minting opened thirty-four minutes later, and all three hundred editions were minted within thirty seconds. That same day four impostor accounts rushed out works under the same name, one of them simply calling itself Che-Yu Wu, and the platform flagged them all as malicious; it was the second time being copied had happened to me.
How the sea grows
One hundred and ten lines cross the picture; each is sampled along the horizontal, its height stacked from two layers of Perlin noise multiplied by a sine wave, and each frame pushes it a little further, so the sea moves; hold the mouse and move right and the waves run four times as fast. The black ground is covered by only the thinnest layer each frame, so the previous frame’s lines linger, every wave trailing the path it came by; lines are blended with screen, and the oil palette switches between screen and normal with the noise. A single white pixel is a splash, its threshold set by the hash; a hundred and twenty small creatures, shells, stars or fish, drift among the waves on the noise. Last, each frame is overlaid with a grain texture the program generates itself, like the tooth of paper.
All seventeen traits are given by the hash on chain: six colour bounds, the palette (colour in two hundred and twenty-five editions, oil in forty-three, mono in sixteen, ocean in ten, silent night and maverick in three each), creatures, stroke, shape, wave noise, vertex span, glitch frequency, two wave frequencies, the splash threshold and the canvas angle. The same hash always grows the same sea.
The lowest-numbered edition of each palette, rendered frame by frame from the exhibition build for six seconds; the lines are the same system, the colours and blending are set by the hash.

Sound
The sound of the sea is not a recording. Pink noise and brown noise each run on their own channel, swelling for four seconds and fading over two, like a wave pushing up the sand and drawing back; beneath them one triangle wave, pitched by the hash to E1, A1, C2 or E2, rises and falls slowly. After Sliderverse this was the next time I synthesised sound directly with Web Audio; only with Soul Fish did real piano samples take its place. The minting build starts to sound on a click; the exhibition and web builds keep silent, because they often run all day on walls with no one at the controls.

Noise
One channel of pink noise, one of brown, each at a low level

Envelope
Four seconds up, two seconds down, a little sustain then release, like a wave up the sand and back
- 03
Bass
One triangle wave, the hash choosing among E1, A1, C2 and E2, scaled by 0.8 to 1.2

Hand
Hold the mouse and move right: the sea runs four times faster and the fish five; P pauses
The renders are the five he chose in 2024 and those in the MONOLAB record; the large print and the frame from Tehran are the two times this sea left the screen. Click to enlarge.
Where the sea has been
At Chaos Laboratory, the first solo exhibition in spring 2022, SoulSea was the first of seven zones, five minutes of ocean life projected beside the digital creatures, Pochi, the snails and the shoals. In The Great Equation in October 2023 it became the scene of the Life chapter, with visitors lying on the floor of Taipei 101 watching the journey run from Island Impressions to the Sea of Souls; in November that year it cycled on the LED wall of the Tech Summit in Tehran. On 29 June 2024 the Sacred Forest concert by PTS and NHK at Liberty Square drove the sea of scene five with live signals, changing its speed and drift; and since August 2024 a purple sea ten thousand two hundred and forty pixels wide has hung as a large print on the wall of Tempo House.
