This animated movie was made for a school assignment. See sketches and storyboards after this "classic animation" (drawing on paper, not Flash). The narration is in Danish, so a rough translation of the Chinese poem follows:
"Once upon a time, I, Chuang Chou, dreamt I was a butterfly, fluttering hither and thither, to all intents and purposes a butterfly. I was conscious only of my happiness as a butterfly, unaware that I was Chou. Soon I awaked, and there I was, veritably myself again. Now I do not know whether I was then a man dreaming I was a butterfly, or whether I am now a butterfly, dreaming I am a man."
