The man featured in the video is named Colin Wright and I was internet acquainted with him at one time. I thought we were kind of friends and ended up feeling burned by him, a story told here.
He's got a few low quality shorts that he probably made. He didn't make the above video, so it's kind of like some album I once owned, bought for the one hit wonder on it and that one song was produced by one company and everything else was produced by someone else and the rest of the album was terrible. So you probably don't need to look for more material by him.
He's not a very nice guy. He burned me and he makes jokes in the video I don't like, such as he does an audience survey and says "You CAN lie." I never liked that joke.
Anyway, THIS video is from the National Museum of Mathematics who invited him to perform in New York and he doesn't drive and he's an Australian living in England and he asked on HN about how to get around New York without a car. I'm one of three people who replied and I replied because it was getting no response since I didn't really have an answer.
So I personally know some of the backstory for how this video came to be and I personally watched this video every night as my bedtime reading for something like six weeks.
This post is NOT an endorsement of the man in question who appears to have inherited wealth, never knew how to turn his hobby into real money, a HOMELESS woman -- ME -- helped him turn it into a thriving business and he did absolutely nothing for me materially and his other videos aren't particularly good.
But if you need free, entertaining, approachable math materials, I recommend this one video featuring him but created by the organization that invited him to perform at their event.
Footnotes
I was often dozing off like halfway through the video. Please don't make this a chore. It's supposed to be an easy, fun way to expose yourself to high level math.
He has a PhD in math and I continued to have epiphanies for several weeks even though I have a fairly strong math background. Also, after watching it the first time, I always skipped the seven minute introduction. I recommend you do the same.
