I recently discovered Caffeine for the Mac and it’s pretty cool. When I’m giving presentations, listening to streaming audio, or performing some operation where I don’t want my mac laptop going to sleep I could mess with the system preferences… Or I could click on a friendly little coffee cup to tell my computer to stay awake. When the coffee cup is full, my computer won’t go to sleep or activate the screen saver. Empty coffee cup means my normal preferences are in control. Nice!

Many thanks to Todd Webb, for pointing this out to me.
