For the OTT swap, I made a miniature cemetery( about 3.5 inches) for my partner. It is inspired by the musicians from the movie "The Nightmare before Christmas".
The three musicians play a discordant tune in the cemetery.
The fish-accordion player jumps on rhythm.
The giant worm-saxophone player swings and rotate from side to side.
The guitarist plays with his hands.
Behind the musicians, there is a willow tree, a red rose grows in front of a tombstone and a skeleton comes dances at the entrance of the crypt.
I made the mechanism from wood, glass and metal.
You can see it move here.http://youtu.be/BOIeA7cJ_ds
