This is awesome, excellent work! Like some others here, I feel like the otters over-engineered the entire thing using fancy glass balls and partitioning a river where a categorized bulleting board would have been good enough.

But then I realized that that's what makes it a realistic story ;)

Jokes aside, the best explanation I've ever seen. It should be a must-do for people who want a quick and understandable introduction to the concepts.
