I believe it was a movie because when I was little I was only able to see it once. It was not animé. I believe the main character was a boy (not sure) who was lost and entered different worlds. He entered the letter world where only letters where allowed to be used - no numbers. And then he went to the number world where only numbers where allowed to use - no letters. the people who lived in the number world was against the people in letter world. I do remember a traffic light somewhere but I really have no idea. Thanks!!
