The rules are simple. Three speakers onstage, one after the other. Each has to speak to a Powerpoint presentation. Each presentation has 12 slides. Each slide is onscreen for 15 seconds. What could be simpler?

Oh, there’s a catch. None of them has seen the presentation before. They’ll each be ad-libbing. Onstage. In front of the Webstock audience and in front of a panel of tough judges.

Yes, this is Powerpoint Karaoke Idol!

Michael Lopp vs Nat Torkington vs Damian Conway. Live onstage. Thursday 14 February at Webstock. Full details here.
