I’m trying something a bit different. Here’s a ten-minute video about a sequence I found on the OEIS.

(I’ve also put this video on YouTube, but I’m anxious about having a copy of my videos somewhere that else)

The sequence is A276573, the infinite least squares beanstalk. The setup for the video was prompted by me realising that my office door is shiny and white, so what’s to stop me using it as a whiteboard?

What do you think? Does the format work? Should I do more like this? What questions about the beanstalk have come to you?
