This is my Stone Age Alarm Clock. Each Cockerel is in a pen made out of sticks. Whenever the sun shines on a Cockerel it will go cockle-doodle-doo. Whenever the sun is hitting the walls of the pen then it will mean it is half past. The sun will come through a hole in the ceiling. This design is a lot like the sun dial but will make sound as well.
