A few weeks ago I gave a talk at the Refresh DC group. I was really excited about this talk for a couple of reasons. First, Jackson, one of the guys on my Wif panel runs the group and asked me to speak. Second, it was their highest RSVP for an event yet. And Third, this was a new talk for me that actually influenced some change in my book. The talk was titled "7 Principles of Prototyping."

Here are my slides.
