Haiku Deck's minimal format encourages concise, bold headlines.
You can import your own photo or logo (http://blog.haikudeck.com/import-images-like-a-pro/) or use the integrated Creative Commons image search for a more visually engaging, metaphorical approach (More about that here: http://blog.haikudeck.com/free-photos-for-all-how-haiku-deck-puts-creative-commons-images-at-your-fingertips/).
This is a great place to link to your event website, collaborative notes, or other resources.
