In trompe l'oeil the viewer must only be
deceived or tricked for a moment.
Trompe L'Oeil Dart and Scoreboard
At first one might notice the dart board is actually painted,
disregarding the dart stuck in the wall.
Once the trick is realized
and the viewer figures out the dart is painted also,
something so simple becomes entertaining.
In other words the instant the deception
or trick is realized actually becomes more of an impact
than the artwork itself. This is what makes a painting,
a trompe l'oeil...the trick and deception,
the moment the viewer is fooled.
