Learn how to make a presentation that only uses a single slide to convey all of your points. This is done using a single mind map and animation to sequence the topics and sub-topics.
Please note that since SlideShare doesn't actually support animation I've had to replicate the effect using multiple slides - so in case you're wondering why the single slide presentation has twenty-something slides, that's why.
If you use SmartDraw you can import a fully sequenced mind map directly to PowerPoint - download a free trial of it by copying-and-pasting this URL:
Clipping is a handy way to collect important slides you want to go back to later.
