Each day of PyOhio ends with a series of Lightning Talks - five-minute presentations on a variety of topics. It's a great way to get a rapid-fire buffet of interesting ideas from all around the Python world.
Lightning Talks aren't scheduled until the conference itself - we'll have a posterboard where you can sign up when you get there. Getting it ready in advance wouldn't hurt, although if you peer at the screen of somebody frantically typing at PyOhio, chances are good that they're preparing a Lightning Talk for that evening...
