I ran across this a while ago, but was recently reminded at the TUAW blog about Caffeine. If you’re nursing an elderly battery like I am, you’re always looking for ways to save power – and having your screen automatically dim after a few minutes helps out quite a bit.  It’s wonderful…until you start to watch a video and the screen dims due to inactivity.  

Enter Caffeine.  It sits in the menubar (a nice little coffee cup icon) and lets you either immediately override screen dimming or set a short term override countdown (say 20 or 30 minutes).  Now you can watch the video and not have to burrow through the System Preferences to disable Screen Dimming…or forget to turn it back on when you leave to get your own caffeinated beverage and end up with a battery depraved MacBook when you return.
