I've got links to the cool 1850s org chart, some info on the Black Rock Rangers, and downloadable copies of my slide deck on my Ignite page.
During the practice sessions, one of the Ignite Boulder organizers said that hat brims tend to hide your eyes. I wore a stovepipe hat and tailcoat anyway, since Decembers are the "dress fancy" Ignite Boulder events. The brim cast a much more notable shadow than I'd expected, but I like the result on the video: my cheeks look kind of washed out, making my eyes more prominent coming from the shadow. I was also really pleased with my delivery: during practice I was constantly feeling rushed to hit my slide timing cues, and worried I'd have to cut a few bits. But when I was on stage I simultaneously felt less rushed and managed to deliver all the material I wanted in each 15-second slide.
