Great Presentations Online
The experts in action:
Is There Life After Death by PowerPoint? (4min)
Very funny look at major PowerPoint mistakes. A quick one to warm you up.
TED Talks: Sir Ken Robinson: Do Schools Kill Creativity? (20 min)
There are a lot of fantastic talks at this website but this one is my favorite. His pace and use of humour is brilliant. This is as good as it gets.
Steve Jobs: Keynote Address 2006 (1h12 min)
No list of great presenters is complete without including Steve Jobs of Apple. This is a guy who is known to spend a LOT of time ensuring that everything is just right. He is the gold standard for minimalist use of slides. Just about any presentation he gives is amazing. I like this one for demonstrating excellent use of visuals... plus he demos great slide producing software.
Guy Kawasaki: The Art of Innovation (54 min)
Kawasaki, IT venture capitalist and presentation guru is famous for his role as Apple evangelist as well as the great 10/20/30 Rule of PowerPoint.
Randy Pausche's Last Lecture (1h25min)
This is probably the most moving lecture you will ever have the privilege to see.
