一个可以在墙面上投射出星星的天球灯。
A constellation light ball that can project stars on the wall.
小时候很喜欢看星星，认识星座，住在村子里夏天晴朗的夜空，满天繁星。如今光污染严重，再也难看到小时候那漫天繁星了。
When I was a child, I loved watching stars, getting to know constellations, and living in a village with a clear summer night sky full of stars. Nowadays, light pollution is severe, and it is difficult to see the starry sky of childhood anymore.
附：天球灯物料，大部分都是可以替换的，不是必选，我自己是趁着手边有的物料做的。
