The idea was to give my child (3 years old) his own clock in his room to see, if it is day or night ('no, it isn't time to stand up! Look, the moon still shines').
The sun shines by day (6 a.m. to 6 p.m.) and by night shines the moon and the stars sparkle.

First, you should create, buy or get a picture which you want to illuminate. I bought some vector-images from Fotolia and arranged them to get my template.
I chose six of the bigger stars to be illuminated and created a drilling template for the wooden frame.
