Focal: Clean the lens, tighten the tripod, setup the light

It was a long a cold night of winter, and I said "Oh,
how cool would it be if I had a better camera!"
The lovely elf came and rang my doorbell, giving me
a package. Inside, there was something I've never
seen before: A mystic cloud where, while inside,
everything becomes possible. Where your wildest
creativity bits become a reality. Rainbows and
pink unicorns, this commit adds Focal to the build.
