Photos of my wife holding the guitar. Sorry the video is so short, but at least you can see the gears move.
The Kickstarter is now live at https://www.kickstarter.com/projects/488929101/boston-metaphysical-society-chapter-5 if anyone is interested in Steampunk comics . . .
Edit: Gaah, can’t get the movie to upload. But the gears rotate and the piston moves.
