Here are some snippets of the Teachers Summer Workshop from a couple of weeks ago (held at Plymouth Congregational Church, which is why you see a cross in the background). No, there wasn't piano music playing in the background in real life.
One of the tricky things about filming puppets with a visible puppeteer is that the focus is off. I teach that the puppet should make eye contact with the audience and the puppeteer should draw the focus to the puppet. When I remember to tell the videographer to come in close to the puppet when it's speaking, the filming works. When I forget, the videographer naturally gets a wider view and the illusion doesn't quite come off. Ah, well.
