Star projector that tells stories
Wouldn't it be cool to not only learn about the stars as a child but to learn the mythology and stories intertwined with them. Imagine going to bed and hearing how Kupe navigated to New Zealand. Watching the stars come together in a story as someone narrates the tale. It could even gently get quieter and dimmer as time went on to lull the child to sleep. Maybe it could be connected to the internet so that the older folk of lots of cultures could tell stories about the stars that were told to them. Imagine Genesis.
In the beginning when God created the heavens and the earth, the earth was a formless void and darkness covered the face of the deep, while a wind from God swept over the face of the waters. Then God said, "Let there be light"; and there was light. And God saw that the light was good; and God separated the light from the darkness. God called the light Day, and the darkness he called Night. And there was evening and there was morning, the first day.
