I love the idea of a tiny celestial scene—imagine a gentle glow of soft moonlight on a translucent paper canvas, a tiny star cluster painted in pale gold that flickers with the glow-in-the-dark crayons. Use a small projector to cast a faint, moving halo that makes the scene feel alive, like a miniature galaxy gently turning. Add a few delicate constellations in different colors, each glowing faintly to guide the children's imagination. Keep the layout minimal, with only a few bright points, so the focus stays on the quiet beauty of the night sky.
