Goodbye World is a conceptual artwork using NFT, animated using the marquee tag, which has been deprecated in the HTML standard for web creation technology. Therefore, this is a work with an uncontrollable lifespan. It may stop working at some point. This is a derivative of the work marquee shelter by 0xhaiku.
