The year 1982 saw three shorts nominated for the Academy Award for Animated Short. All were excellent and could easily have won. It was the misfortune of The Great Cognito and The Snowman that they were in direct competition with this short. This is so intricately done and so fascinating in its conception and execution, that words fail me. It reminds me of the feeling I get when I look at the works of M.C. Escher. This must be watched (more than once) to be fully grasped. One warning is necessary: this is not for children. A portion or two of this is most decidedly adult in nature. Most decidedly and solidly recommended!
