Presented at GoGaRuCo 2010 as a 4 minute lightning talk to a room full of 300 programmers. In San Francisco, CA on the UCSF campus. I've seen bad slides at nerd confs for years.
I'll be growing this out into a 30 minute talk to give at other conferences. I'll link to the video when it's up too.
If you want me to present this at your conf, get in touch. Also, I'm available to punch up your slides before you present them at a conf.
