Pictures from the lecture can be found here.
Here also is a brief video of the after-lecture signing.
And I should soon be able to post a link to a place where you can download the audio from the lecture too.
The lecture went very well. We had about 65 students show up, and the students hung around after the lecture--asking questions, buying books, getting sketches--for about two hours.
And each one of them, when they would get a sketch, would run over to me and say, "Mr. Higgins! Check out the sketch I got!" I felt like a proud parent; I wanted to ruffle their hair and pat them on the head afterward.
