So for the past two weeks, I've been buildig a music box based on fnaf2 as a gift for my sister's birthday. I based it on
this one and used their tutorial as a guide. It was a LOT more work that I thought it would be, but turned out great. Here were the final pics:
It has a crank on the back, and plays "My Grandfather's Clock," which is the song it plays in the game. The puppet spins while it plays, and everything stops while the box is closed.
Here are some in-progress images:
