A cute and useful menu bar application for Macs: Caffeine, available in the App store.

If you click the little coffee cup in your menu bar (so that it’s full), it will prevent your Mac from displaying its screen saver or dimming its screen. This is especially useful when you’re giving a talk.

    Andrew Gelman posted on the same topic 7 minutes after me. His post is better the mine, because (a) his title tells the whole story, and (b) he explains the problem before stating the solution (in contrast, I say “here’s a cool program” and then say what it’s good for).
