Arsenal of Democracy: The Overhead Projector

Like most of you, I'd seen signs hung over the freeways before. They were usually made from bedsheets or butcher paper and painted with messages that were sloppy if not unreadable. They were usually hung on the outside of the fencing, directly over the traffic, which is both hazardous and entirely unnecessary. By using an overhead projector and cardboard I found it easy to make signs that were entirely readable and stayed that way. Putting them on the inside of the fencing instead of the outside reduces the chance of their falling into traffic to precisely zero.

The awesome power of the overhead projector for signmaking cannot be overemphasized. It takes anything you can type on your computer - any font, size or style - and makes it huge. Simply print onto a transparency, place on the projector and shine onto your canvas, trace the letters and then paint. Works for logos and simple graphics too.
