This short (under two minutes) presentation uses only narration and text to make its point. I'll make no comment on the twist so as not to give it away. Watch it below or on YouTube.
The presentation above has made an impression on many people (I sure keep hearing about it). The original concept, as far as I know, came from a 2006 Argentinean political ad (see the ad here). The "Lost Generation" presentation placed second in the AARP U@50 video contest (odd: it's better than the winning video in my opinion).
The video is well done and makes for a nice stand-alone presentation. It could be better: For example, the text needs to be a bit bigger — never make people strain to see the text on screen. Also, sans-serif typefaces are usually preferable in this kind of situation as they are often more robust. The serifs in a seriffed typeface tend to lose their integrity and get rather pixilated at smaller sizes on screens and in compressed videos like this. Still, this was a creative way to deliver an important message.
