Thank you very much who all attended my day long seminars in Portland, OR and Seattle, WA for Oregon and Southern Washington Oracle User Groups (OSWOUG). Listening to one speaker for 5 hours definitely was not easy. I understand that and appreciate your gesture.
Attached please find the various slides and scripts I used in the demo (Remember: this is a 2 MB file).
