That was absolutely awesome!<p>I haven't done one for a while but I used to really enjoy giving "lightning talks" (which was the same idea, a 5 minute talk about just about anything). The thing that was so fun about them was that it really was a performance more than just a talk - to do a good one required a lot of thought and planning for how you were going to get your point across in 5 minutes. And the nice thing was that rehearsing the talk only took 5 minutes, so you could really practice it a lot and get it nailed down.<p>I gave a few conference talks too, usually an hour long slot - and those were fun in their own way - but geez, rehearsing it more than once or twice was just too much time.
