This photo is from an area flanked by a Library and some other buildings, including the building on the left where the lecture was held.

As you can tell, Derek and I did not arrive early enough to get a seat in the auditorium. This is the slide from the talk that discusses various features of other languages that Perl decided to use or not use.

The lecture hall was so crowded that people had to sit outside in the hallway to see the lecture on television. The audio was really difficult for me to hear.

A (sort of) close-up of Larry Wall from just outside the auditorium.

This photo of Larry Wall and a slide discussing natural language concepts implemented in Perl was taken from another entrance to the auditorium that myself and some other people found.
