When it was drawn

What this page states · not a verdict

Drawn in 15k strokes over 04:08:05, across 94 sittings (over 24 days). Whether external images were imported is not checked in this record (v0). The record alone allows it to be replayed from the beginning.

View habits

While drawing, the canvas was rotated 217 times, zoomed in 111 and out 91 times — traces of working at comfortable angles and scales, recorded as part of the working habit.

Forgery difficultyVery high93/100top 22% hardest to fake

To forge this process exactly, one would have to reproduce the pressure, timing, and tremor of all 15k strokes — one by one. This isn't a verdict; it reflects how dense the recorded signals are.
