To show just how much of a lunatic I am, today while surfing around, I was trying to remember what the gadget that caused the puppeteer's voice (or, more properly, the Professor) of a Punch and Judy show to sound the way it is. A bit of searching reveals that the device was called a swazzle, and turned up this page of interesting links regarding Punch and Judy shows.
Why was I thinking of this? To be honest, I have no idea. I can't reconstruct the path of my thoughts that led me to think of this. Nor can I imagine why I would find this information useful. I'm one bizarre monkey.
Just a fun link of the day: a Mechanix Illustrated article on making home made 3D movies.
