NEW! You can now watch more Farey-Ford math on Youtube!

I hope that, in addition to the french accent and other idiosyncrasies, you enjoy the math and the fantastic editing work of Brady Haran. The math videos of his  Numberphile channel are really great. It seems that this video was watched by 160,000 viewers in its first month on the Internet; now over 230K views.
