Another Numberphile animation here for a video about the Stable Marriages Problem, featuring Dr Emily Riehl. All the wee people are hand drawn, composited and coloured in Photoshop and animated in after effects. I really like the little village of people, not entirely sure about how well the Jane Austen characters came out, perhaps making Collins a bit too mole-ish. Brady wrote a blog about them here.
There’s also an extended mathy bit below if you’re interested.
