Paul,

Exceptional work as usual for you! At first I thought maybe you had made the Jack-in-the-box with your fully hinged, take-apart box and wondered how Jack would work with the box taken apart. Your puzzle idea is very creative.

I’m assuming the black box at the bottom of your post is a video (which I can’t watch on dial-up). Does your Jack-in-the-box play “Pop! goes the Weasel”?
