Math is way more fun when it's lent some narrative, some purposeā€”and we've never seen a better example than this stunning noir cartoon which explains fractals. You have to watch it.

As Brot tries to save the dame, he faces geometric riddles and tortuous math. This is The Case of the Missing Fractals. [TED-Ed]
