In the anime series Naruto, ninjas use 12 basic “hand seals,” or simple gestures named after the 12 animals in the Chinese Zodiac, to fight their enemies and do ninja stuff.
In the show, the characters fly through sequences of signs wildly fast, so if you’re trying to learn the sequences—as a lot of fans who you’ve probably seen wearing Naruto headbands in public do—being able to test your accuracy could help.
