This short film for kids offers a lesson in proportions in which simple actions achieve surprising results. A man wants a door in a wall. He draws a rectangle and, presto! There is an opening. In the same way, he conjures up furniture. If too high or too low, the raising or lowering of a finger puts everything right.
