Everyone loves looking at the stars. Unfortunately, city lights, clouds and pollution often prevent this from being a frequent passtime. This instructable helps capture some of the beauty and most of the romance associated with the heavens and puts it on your living room or bedroom ceiling.
The premise is simple. Make holes in a bowl and shine a light behind it to make stars on the ceiling.
The completion is quite a bit more complex, due to some pesky laws of physics that I'll explain in the next few steps. The end result is a curious looking device that will definitely get lots of remarks, especially when you turn it on.
Unfortunately I didn't think of making an instructable for this until after I had completed the project. It was a gift for a special someone and I didn't want photographic evidence being accidently discovered on my computer or her camera. I'll try my best to be comprehensive and thorough with the pictures I've taken.
This instructable makes minor assumptions that you have basic soldering skills and knowledge of how to use hammers and typical hand tools.
