The Butterfly is a character searching for happiness. When he finds it, the film continues but the action stops. A tranquil musical score lulls the viewers who watch the animated picture of an unending happy ending, which may be pleasant enough for the character but ends up boring viewers.To escape the boredom, the viewer can trigger action by pressing a button, whereupon the character reassesses his life and sets off in search of something new: he becomes a politician, a priest, a vagabond… There is also a non-interactive version of The Butterfly, titled The Inconstancies of the Butterfly.
