He said he would never sell. NOT ONE SATOSHI #128 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 lower left while everything behind it swings. Rendered in One Satoshi — hard black and white, pixel-sorted, with a single orange square somewhere in the frame. One satoshi: the one he said he never sold. Cut at 13.23s, in Act IV, The Descent. Depth lock 1.59 — Standard. Active brightness flicker. Its four source frames are shared with another piece in the edition, converged on a different point — the same instant seen from a different lock. 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.
