If you’ve ever wondered why every version of Hokusai’s “The Great Wave off Kanagawa” feels just a little bit different, this video from the British Museum is a gem. It dives into the subtle variations across 111 known prints and shows how art, time, and technique all leave their mark.

Capucine Korenberg from the British Museum spent over 50 hours just staring at different versions of the print, joking “This is about the same amount of time you would spend brushing your teeth over two years. So, next time you brush your teeth just think of me looking at The Great Wave.”
