Here’s a sneak preview of my new video with Steve Mould. Let me know if you spot any major mistakes.

It will go live 3.5 hours after this post has gone up (at 14:00 in the UK, 9:00 East coast USA). Please do not share it before then.

Recursive PowerPoint Presentations [Gone Fractal!]

Thanks to Steve Mould for filming with me. Check out his "How viruses self assemble" video. https://youtu.be/3X6qEE2fHvE We have some free teaching resources for anyone who wants to make a large collaborative fractal! As well as complicated 3D ones we've made a new Think Maths "low-prep giant Sierpinski triangle" guide. http://think-maths.co.uk/standupmaths-videos?yt-PPT-fractals#PPT-fractals The second channel video takes a closer look at the pptx file and the details of what version of PowerPoint you need to make this work. https://youtu.be/5Mltw6cTb-s If you want to see the live An Evening of Unnecessary Detail show: it's once a month in London. https://festivalofthespokennerd.com/show/an-evening-of-unnecessary-detail/ Some technical details about the Cantor Set. http://mathworld.wolfram.com/CantorSet.html CORRECTIONS - Nothing yet. Let me know if you spot anything! Thanks to my Patreon supports who do support these videos and make them possible.

I would of been curious of the memory usage through all this. I suspect you may eventually with enough presentations cause power point to crash.

Glenn Watson

Based on the video though (since I made the first comment before finishing), it seemed you were more CPU bound. I guess that makes sense since you're doing exponential operations so probably NP complete problems.

Matt Parker

Yes, even though YouTube will claim an upload has finished processing: it actually takes quite a while longer for the HD and 4K versions to be available on all its servers.

Matt Parker

Did you check out the second-channel video as well?

Glenn Watson

Yep I didn't thanks for pointing it out

Dr. Martin Borchert

Really amazing video! Did you see the video with the Turing machine in powerpoint? And of course: First question: Where to buy the t-shirt?!

Oh... Sierpiński's triangle! What a polished presentation ;)

Richard Breen

Hi Matt. I think that the command in the second channel video is not quite right. Everything up to and including the ">" symbol in Steve's command window is part of the terminal prompt, and when you paste that in windows won't recognise the ">" at all. I think that if you replace the ">" with a "\" it should work.

No mistakes in the content, but the music does stutter slightly on the edit at 14:34... not sure if that's significant enough to be a problem...

Hi Matt, I replicated the triangle fractal on Power Point, if you save and close it just after deleting the first triangle, and then open it, the fractal appears with several iterations, not all ok but interesting enough

It’s strange seeing you begin a video in front of those familiar red pipes.
