Hello, this is not my work, and I am not a puppeteer. This is actually a piece by Hobey ford. He recently performed this piece at the National Puppetry Festival, though this video is not from that performance. You can find him with a quick google search.
Really like the look of your shadow puppetry - we'd love to see you perform. We also make shadow-puppetry (The Clockwork Moth) if you'd care for a look, and I can see that you've made similar observations about what is possible when puppets are fixed to a set. Really nice work - keep it up.
