"RIP Skeleton" is a 3D printed Halloween themed "Do Nothing Box". Simply press the red button, and RIP Skeleton arises red faced from his candle illuminated coffin to "press" the red button and return to darkness for his "rest in peace".

The design is reminiscent of the electro-mechanical pinball machines I repaired for a local entertainment distributor while attending college some 40 years ago (we still have a fully functional electro-mechanical "Captain Fantastic" pinball machine, circa 1976, in our game room). Instead of a using a micro controller and servos, this electro-mechanical model uses a single motor and a two lobe camshaft to control the simple animation and lighting via two micro roller switches following the camshaft lobes.
