Here's a short animation I wrote and produced with animator / illustrator Andrew Khosravani. The piece is narrated by Hannah Fry and tells the story of how zero became a number. We were very happy about it getting a "Staff Pick" on Vimeo!

The scripting for the piece was tricky, it took several weeks to wrap our heads around the subject and then boil a significant amount of history down into around 3 minutes... inevitably details had to be cut and even after recording the voice-over with Hannah we had to make some difficult decisions to make further cuts. All in the name of reducing animation time - which was significant for a piece like this - Andrew did an incredible job!
Oh and the chapter numbers are obviously all in binary.
