He said he would never sell.

NOT ONE SATOSHI #001 is a stereoscopic wigglegram, built from four frames of a 21-second animation sampled every 4 frames and looped 1-2-3-4-3-2-1. The subject is pinned at lower right 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 0.13s, in Act I, The Face. Depth lock 2.49 — Deep. Low 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.
