Before multimedia displays and PowerPoint presentations, fundamentalists had chalk. Credit where it’s due, if done well, chalk talks were a great way to keep people’s attention and make a point. If done badly, however, the presentation may end up looking vaguely like a cubist artist’s impression of a sunset at the North Pole. In short, it’s a royal mess.
In the really extravagant chalk art presentations, a black light may be used to reveal hidden images at the end of the talk. Or perhaps, the artist would draw upside down and then later reveal the real picture by flipping over the canvas. Not too many people do this anymore; it’s really a shame. Watching someone doodle on a screen in MS Paint just isn’t quite the same.
If you’ve never seen a chalk talk done, you can check out a video of none other than Peter Ruckman giving a presentation while drawing an “original autograph.”
