When it was drawn

What this page states · not a verdict

Drawn in 11k strokes over 04:01:56, across 320 sittings (over 4 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 108 times, zoomed in 176 and out 84 times — traces of working at comfortable angles and scales, recorded as part of the working habit.

Forgery difficultyVery high80/100top 38% hardest to fake

To forge this process exactly, one would have to reproduce the pressure, timing, and tremor of all 11k strokes — one by one. This isn't a verdict; it reflects how dense the recorded signals are.
