This work is the second in the Reference series of “Sculptures that Possess Themselves.” Inside this camera is an NFT that proves the possession of the camera. With this NFT, the camera possesses itself. The following structure of reference realizes this possession. “→ Camera → Film in the camera → Seed phrase captured on the film → Wallet generated from the seed phrase → NFT in the wallet → Photo attached to NFT → Camera in the photo →” If you view this work through the concept of reference, you will notice that this structure can also be referenced from the outside.
