Memory Disc" is the first work of media artist NIINOMI's "A SYSTEM" project, in which computer systems are used as art, and is modeled after a CD as a storage medium that records various attributes.

marquee shelter is a project to bury obsolete web technologies in the blockchain. The animation of the work is created using only the marquee tag, which has been deprecated from the HTML standard for creating websites. It has a life span that cannot be controlled, as it can stop moving with browser version upgrades. It is a life-like device on the blockchain, which is expected to be eternal, and evokes thoughts about technology and life.

Receipt is a conceptual art using NFT. The visual is determined by the amount you pay. You can pay any amount; you can mint (create) one token per price. All the code to draw is stored on the blockchain. The transaction itself is your participation in the art. The reality of the value of NFT is the exchange of data on the blockchain, which is used by many people who trust it. 0xhaiku believes that the memory of the act itself is the new value of art.

Recycle Bin is conceptual art using NFT with the theme of rebirth. By sending unwanted NFT to the Recycle Bin address, the NFT will be Burned (discarded) and you will get the Recycle Bin's (trash bin) generative art NFT instead. New art will be generated based on the sent NFT. The pain of confronting the past and a prayer for rebirth are expressed.

Advertise" is a project that uses a "signage system that allows you to advertise any URL you want without censorship". The wallet used to post the URL will be sent an NFT (Non-Financial Transaction Format) certificate of advertisement.

In order to post a URL, you must have paid at least "the amount paid for the last post" (+ gas fee). This amount will be reset at 0:00 JST. If there are multiple submissions in a short period of time, the URL with the highest amount paid will be displayed. Other URLs may not be displayed.
All proceeds will be returned to the gallery during the exhibition period.

HODL is a full on-chain NFT that grows with the duration of ownership, and its growth is reset when the money is transferred from the wallet.
This work expresses the subjective value felt by the owner, as opposed to the objective value determined by the market, through the experience of owning an NFT with time.
