# Note: As of right now, you will need to selectively comment out loops one at a time to layer them correctly. I am still learning about how threads work in Sonic Pi, which seems like it will eliminate that overhead.

# Note 2: This is the "live" demo I gave at the Boston Ruby Group lightning talk night on 08/13/2019.
