To have Adobe Reader auto-advance your slides for you, go to Adobe Reader’s preferences, click on Full Screen under categories, and then look for the Advance Every check box and type in the time interval.  Magic, you don’t have to touch anything and the slides will automatically proceed when you want them to.  Remember, a Pechakucha advances every 20 seconds, so that is how we will be conducting our half-Pechakucha for the reveal.
