Hangman Prop
Ulcerative has posted a great video of the perfect frame for a hangman prop. When the attached wiper motor is turned on the flailing effect is supreme, and even though it’s just a PVC frame in the tutorial, you can more than visualize the awesome effect you’ll get when you clothe the frame and light it for effect. If you don’t want to get into pneumatics, but still want a great visual, this is definitely one you’re going to want to try.
