I recently gave a TEDx Talk entitled: "We Are Alive" at TEDxSBU in New York. I used Haiku Deck to create slides in anticipation of the event, and then went to Flickr to retrieve the actual Creative Commons images from the slides, added a Haiku Deck-looking template to PowerPoint, and developed a deck for my 1080 HD presentation. I delivered the talk, and it is available online at: http://bit.ly/kent-ted
This is my (much simplified) method of creating slides for a TED Talk using Haiku Deck!
