Create an animated clock in R with ggplot2 (and ffmpeg)

Because it's Friday—and I needed to create this for a separate visualization—here is how to create an animated clock in R using ggplot2

I think this is a nifty way to show time elapse, rather than the windowed timelines I had used previously. Enjoy.

P.S. I will be officially off the grid starting now until mid-September. See you on the other side!
