Presenters can download a PowerPoint template here:  GCSC lightning talk template. The presentation includes 8 slides.  The first is an untimed title slide to introduce the presenter. Six subsequent slides are timed at 30 seconds each to total 3 minutes. If you need more than 30 seconds to make a point, simply repeat a slide. The final slide allows up to two-minutes for one question from the audience and a response.
