I assume then the followup question would be why they’d be using a timer while drawing. If it’s at a convention I could then assume they might do small commissions for people and use the timer to ensure they draw them quickly and don’t spend too much time on each drawing.
Not at convention, more like that exhibition. There are no artist do commission.
The machine (timer) i show you are work tool of an famous artist. They put all his work tool in glass box for people to see.
I wonder if the artist was a fan of the pomodoro technique?
Maybe to bill them.
It is the same when developer use time tracker to do freelancer job. The job is billed by hours.
