Fragment Lock is the Genesis piece of Rare Pattern Signal, Signal #001, dated October 13, 2026. A field that will not sit still. It bends, it drifts, it comes apart. Most of it lets go. What remains, holds. The work ends in the artist's signature. Sound and image grew from the same code. One chord, held. Then light. That chord became the music of rarepatternsignal.com. Sixty seconds of generative art by @RarePatterns, held to orange and black, a palette chosen by eye before the code was written. Every frame is generated by the code. While it waited, a seed head grew on the site a little each day toward mint day. Edition of 5 on Ethereum: 4 offered in 24-hour auctions, one every other day from November 2, and 1 kept by the artist.
