If you have ever done a parachute jump, gone on a really big waterslide or pushed the gas pedal in a porsche you know that feeling of traveling in lightning speed and how it makes your body feel like its full of fireworks! Listening to David Chapell is like taking that trip in you mind, in that speed. Usually towards the future.
After teched I tried to describe what it was like to listen to David Chappell speak, the parachute feeling was the closest I got. I really think that everyone who has a chance should listen to David speak, couse he certainly knows how to do it and on top of it he usually has something to say as well ;)
