Abstract
This is a work expressing a collapsed world through sound and visuals in code, and is a digitally native animated piece. At its root are my doubts about the permanence of digital data and nostalgia for bygone days.
Please note that this work is a digitally native animated piece and is not suitable for static images. I would like you to view this work with the room darkened and the display set to full screen or projected with a projector. Then click on the piece to play the wave sound and take the time to experience the interaction of the visuals and sounds. Since it would be impractical to store huge sound data on the blockchain, the sound was generated from white noise.

Background
When I started using a computer, I believed that digital data could be stored forever. I saved my favorite picture files and small freeware programs to floppy disks with a capacity of roughly 1 megabyte and stored them carefully. Those floppy disks were my treasure. Later, when the disks deteriorated and became unreadable or were lost, the data became memories with a deep feeling of loss. Even when high-capacity hard disks became widely available, the data again became memories accompanied by a great sense of despair when hard disks crashed or were accidentally formatted.

When the Internet became popular, I browsed various websites using Netscape. The contents, now cheesy but lovable, were created by individuals. I believed that if I added a website to my favorites, I would have access to its content forever. But one day, the site suddenly closed, and the content became a memory.

Fortunately, some data continued to be saved. Feeling nostalgic, I wanted to take a look at it after a long time. However, I could not open it due to differences in the OS or software itself, or in the version or format at the time. Even if the data itself is saved, it has become a memory because of the loss of the execution environment.
Fragmented memories about the data. Vague shapes. What I believed to be an eternity suddenly turns out to be a fleeting dream. Looking back later, the sadness of loss fades and the memories of happy times remain. It's all in my mind.
Do digital data exist in digital space? In reality, they are merely recorded on some physically existing media in physical space. The data that exist in the cloud are stored on servers, in buildings somewhere in some country, even though they appear to exist in digital space. Any material that exists in physical space will always deteriorate. What appears to exist forever is maintained, including backups, at great cost and effort.

Blockchains have arisen. Are these truly persistent? The persistence of a blockchain is maintained by multiple factors. When there is no longer a reason for these factors to work, the chain will collapse.
More simply, the day may come when humanity runs out of resources and electricity is no longer available. A major climate change or war could eliminate everything. The period of time in which an advanced civilization can be sustained is surprisingly short. There is no such thing as permanence.
After all, digital data are also a type of memory. They are stored in a person's mind, deteriorate, and one day will be lost with that person.
I find fragility and beauty in them.
Description
In this work, I attempted to represent a fictional collapsed blockchain world with visuals and sound.
The chain has already been abandoned, and the few nodes that remain barely alive are just maintaining their appearances. Visualizing the remnants of blocks that no longer serve their original purpose, they form something like a submerged city. Then, a large amount of data that has lost its connection to the blocks and has deteriorated to the point that it can no longer be opened flutters through the sky. The countless remnants of data form a cloud, which undulates like a wave. The details of the data cannot be confirmed; however, they can be seen as glittering lights. As I try to recall the contents of the data that can no longer be opened, I am filled with vague memories and a sense of nostalgia.
This work started with generating sound by code. The sound of rippling waves can be heard by clicking on the screen. Since it would be impractical to store huge sound data on the blockchain, the sound was generated from white noise. In order to reproduce the sound of rippling waves, it was necessary to deepen my understanding of the structure of sound by referring to academic papers. Then the sound was completed, and the visual imagination expanded from there.

I like to visit the sea near my home and in other places. Different seascapes can be seen from different locations and angles. When I am there, idly gazing at the seascape and listening to the sound of the waves, I sometimes feel as if I am the only human there and that the world has gone to ruin. If the world were ruined, this seascape and the sound of the waves would remain for a long time. This feeling, and the fragility felt in digital data, are the basis of this work. I imagine that the heaven or the graveyard where the lost data flies up into the sky and arrives may be a seascape like this.
The reason why I used data as lights and clouds drifting in the sky and moved them like waves is that I wanted to depict unrealistic behavior with a realistic subject matter and to express a beautiful and bizarre world in which these intertwine.

For the visual expression technique, I further pursued and evolved the drawing system that I have developed in "GHOST IN THE CODE" and my other works. Everything is composed of rectangles to evoke the digital and the pixel. Depth is linked to the size of the rectangles, and distant objects are represented by small rectangles as if they were in focus. Dispersion in the position and color of the rectangles indicates the degree of deterioration of the world. Moreover, the sky, the blocks, and the surface of the water are identified, and each has its own characteristics.
Algorithms generate various compositions, colors, and other features. I have attempted to make each output feel nostalgic and fresh at the same time. The blocks, which have lost their original meaning, are contrasted with the data, which exists in isolation from them, in stillness and movement. Occasional red clouds or blocks mean that they are rendered as red, the first color, due to missing information.
Through these integrations, I have attempted to create a work that can be stored on a blockchain and that is both visually and sonically interactive.
