When it was drawn

What this page states · not a verdict

View habits

While drawing, the canvas was rotated 0 times, zoomed in 0 and out 1 times — traces of working at comfortable angles and scales, recorded as part of the working habit.

To forge this process exactly, one would have to reproduce the pressure, timing, and tremor of all 491 strokes — one by one. This isn't a verdict; it reflects how dense the recorded signals are.
