The welding projector
This trick was invented and produced by Harry Kentrotas and Simon Dunckley from Cape Town. We used the trick in several shows during 2002.
You need an arc welder. It’s not only useful to do metal work but can also be used perfectly as a light source to create a shadow puppet story: very bright, and within an actual light source less than a centimetre across.
The distances between the light source, the puppets and the projection surface (a wall, a container, etc.) can influence the size of the projected shadows, but doesn’t effect the sharpness: there’s always a clear-cut shadow. To prevent the audience from looking into a light that is far too bright but to allow them only to enjoy the projected images, we welded it in a small wooden box. In that, we cut out a small window, which defines the frame of the projected surface. Read the rest of this entry ?
