On Monday, we posted a great collection of Japanese Rube Goldberg machines which commenters inform me is from the Japanese educational show Pythagoras Switch. But if you think that clip was catchy, check this out: Algorithm March... With Ninjas.
As near as I can tell, they aren't marching or singing about a mathematical algorithm, but some sort of Japanocentric protocol of politeness. Manners, math, it doesn't matter: ninjas are the right instructors to teach kids about just about anything.
