The original plan was based on just this simple design, but my over caffeinated imagination couldn't stop there. It decided to go high-tech on this one. Added to the design was a motor to turn the mobile, a light to charge the glowing material and some additional components to trigger some action. The cherry on the cake is to synchronize this behavior with a spooky sound track.
This instructable will walk you through all of the steps to replicate the entire project. However, you can alway stop at any step from just printing off a ghost, to just building the mobile or taking it all the way to the end.
