He said he would never sell. NOT ONE SATOSHI #121 is a stereoscopic wigglegram, built from four frames of a 21-second animation sampled every 2 frames and looped 1-2-3-4-3-2-1. The subject is pinned at upper right while everything behind it swings. Rendered in Balance Sheet — a photocopy of a photocopy. Roller bands, xerox blotch, dot gain. The document after it has been through the machine too many times. Cut at 12.53s, in Act III, The Ledger. Depth lock 1.69 — Standard. Active brightness flicker. Depth lock and flicker are measured on the master render, before the tier treatment is applied — so they describe the stereo capture itself and stay comparable across every tier in the edition. One of 210. The complete 21-second work exists as a single 1/1.
