I saw Waking Life on the independent film channel a few years ago and it just grabbed me. I love art and unique mental stimulation and this film appealed to both. The movie was first filmed and then the art director himself created a computer program to animate the film in a new way. The art was created through a collaberated effort of a few artists.
If you are interested in philosophy, lucid dreams, or the possibilities of the human spirit than you will enjoy this film. Even if these topics dont necessarily appeal to you, than the visual content will capture you.
