This violin makers shop by W. Foster Tracy, is a miniature built inside a full-size violin. It was on display at the Mini Time Machine Museum of Miniatures, Tucson, Arizona. All completed instruments and tools are fully functional in this model.
I miss being in orchestra-- violin is an instrument of perfection, because the more correctly you play it, the more beautiful it sounds. My favorite teacher told me to "pull the music out of the violin, not just play"
