Years ago, I saw someone demonstrating an obscure slide presentation system, and one of the tricks it had was to let you draw on slides with the mouse. So you could underline or arrow specific points, or, more important (since underlines and arrows are easily included in slides), draw something in response to an audience question.
Neat feature, but there were other reasons I didn't want to switch to that particular slide system.
Curled up in front of the fire last night with my laptop, it only took a couple of hours to whip up a proof of concept that seems remarkably usable. I've added it to htmlpreso.
I have to confess, I've never actually felt the need to draw on a slide during a talk. But I still love knowing that it's possible. It'll be interesting to see how often I actually use it.
To play with drawing on slides, go to my
and, on any slide, type Shift-D.
Some color swatches should appear in the upper right of the slide,
and now you can scribble over the tops of slides to your heart's content.
