Day 24. I was out and about in San Francisco most of the day, so didn't get started on this until I was finally in the MAX on the ride home from the Portland airport. I started this on my phone, which meant I was relatively limited in what I could do, so I started putting some loops from Garage Band on the iPhone together. I never made it an explicit rule not to use loops, but I've always felt bad about doing that. This one is almost entirely just various loops assembled together. But it was more important to me to get something done than to not use loops, so here we are.
