This interesting Ignite presentation (5 minutes preso, with 20 slides that advance automatically every 15 seconds) by Tom Scott was recorded at Ignite London in March 2010. Scott talks about a Flash Mob that goes wrong… or does it? I liked his storytelling and the visual aid of his slides. Most importantly, I appreciated the method he chose to make his point. Recommended watch… and btw it will only take 5 minutes!
