This video created through the support of my patrons, with special thanks to Ray Sidney, Andew Romaner, Perryman, Carol Hart, Pat Devlin, David Smith, and Yana Chernobilski.
The shape name "Scutoid" was coined in 2018 by this paper: "Scutoids are a geometrical solution to three-dimensional packing of epithelia" nature.com/articles/s41467-018-05376-1
3d printed models shown:
Scutoid Pair by Laura Taalman: thingiverse.com/thing:3024272
Scutoid, Four Cell Configuration by John Peplinski: thingiverse.com/thing:3033602
Scutoid, Space Filling Duo by John Peplinski: thingiverse.com/thing:3042446
Scutoid papercraft models are a collaboration between myself, Laura Taalman, John Peplinski, and Tom Ruen. The next video in the series will have instructions to print and make them yourself, or in a group where everyone's scutoids fit together!

If you didn’t see it, don’t feel left out. You can experience existential horror in the comfort of your own home, irrespective of the alignment of celestial bodies!
This is adapted from a piece I wrote in 2017 after the August 21st total solar eclipse, which I saw in Oregon. Posted in honor of the 2024 total solar eclipse on April 8th.
Thank you to my Patrons for funding the creation of this video. Extra special thanks to Ray Sidney, Andew Romaner, David Perryman, Carol Hart, David A Smith, and Yana Chernobilsky.

I know this is a weird video but I can’t help it, moon spoon delights me.
Thank you M, Darla, Erin, and Michelle for giving me permission to include your moon spoon content!
M can be found at: http://blinkpopshift.com
Michelle’s original moon spoon comic: instagram.com/p/CjYZVVLLFsa
The original moon spoon booklet can be found here: docs.google.com/presentation/d/1taYSxa34L8McNRhhQr-RqiUcjw4gRTyMPopvm-ngkLg/edit?usp=sharing it’s formatted for printing, so the pages are out of order. Check the notes for instructions.
Moon spoon is a fun creative and self-reflective activity anyone can do at home, and with my people I've found moon spoons to be a good opener for conversations about what's going on in our lives and in our heads.
Statement on Gettin That Sweet Sweet Moon Spoon Money:
“Moon Spoon is never the same,” which is why I decided not to mass produce and sell moon spoons. Also there’s some bad practices in the uh, magical things industry, that I’d like to avoid. So make your own, or make them for each other! Selling/buying them is fine too, as long as they are hand made with love and intention. You have my permission and blessing to make, share, sell, etc, with moon spoon, including the moon spoon booklet, as long as it is YOU making and selling them (not using a manufacturer or outsourced labor).
Also note: vials of moonwater are very fun, but are likely to leak or explode, so don’t ship them or carry them around in a pocket with your cell phone unless you’re really sure about your materials and methods. I speak from experience.
This video was supported by Patreon! Thank you to my patrons, who are used to being thrown curveballs in terms of the kinds of things I post, yet still perhaps were not expecting moon magic... hehehe I hope you like moon spoon anyway! Extra special thanks to Ray Sidney, Andew Romaner, David Perryman, Alan Boulton, Carol Hart, David A Smith, not lesia, and Yana Chernobilsky.

Bonus exercises for those who absolutely will continue to overthink this for the rest of their lives:
1. If you have a 150 light strand with 5 “Christmas” colors, and decide to remove all the pink ones and make it a 4 color pattern, what’s the minimum number of lights you’ll have to replace/move? Can you generalize to any number of lights and colors?
2. Choose, or create, a holiday that doesn’t have string lights as part of its standard decor… yet. Decide what colors the lights should be, considering how the colors will mix and light the room. Get as detailed about frequency, spectrum, and incandescent vs led considerations as you want.
3. Remember how you could think of chasing light patterns as moving slowly in one direction, faster in the other, or even faster in the original direction? How far does this go? Can you come up with a way to describe this, for different numbers of lights and different chase patterns?
4. Create something that has the vibe of string lights with different colors and chase patterns. Use a musical instrument, a computer program, makeup, dance, or any medium you enjoy. It could use simple blobs of color, plain text numbers, sounds, or movements.
5. Say you have 3 spider light factories, each of which exclusively makes one color of light: orange, purple, and green. If you are producing 3 different colors for 10 bulb string lights that start and end with orange, how much efficiency are you losing by having idle factories that don’t need to produce as many purple and green spiders?
6. Prove irrefutably that spiders are a christmas animal.

Hey, I made a video! Thank you patrons for supporting and encouraging me. I had fun with this one.
Uhh there is probably more to say but it's been a while and I forget how to youtube
Usually my videos are funded by Patreon, but this one isn't, because that could be awkward for the folks I might usually name as funders. So. Patreon payments are suspended for this one. And since I don't make money on youtube or run youtube ads, this one's just a quick low-budget statement for those who are wondering my position on this issue. Now you know!
Chicken salad includes:
Half mayo, half yogurt (for sandwiches, lean toward mayo. For eating straight, lean toward yogurt.)
Celery, green onion, apple (grapes work great too)
freshly toasted slivered almonds (this is like the tastiest secret to great chicken salad)
seasoned to taste with salt, pepper, mustard, turmeric, cayenne, whatever else you want because it is your salad and you deserve delicious snacks

I learned this from Mike Caputo in around 2010, and as far as I know he originated this trick, or was an early popularizer of it, in his 1990 article in the Jan/Feb edition of The Oregon Mathematics Teacher (and if anyone can find this article maybe it will give more insight). I blogged about it in Feb 2011 after teaching it in a workshop when I was Mathemusician in Residence at Harvard's Pforzheimer House (anyone here from those days? Hello!), but unfortunately all the links in that post are now dead (as is the blog itself) and my memory is fuzzy. So if you have info to share please send me a note!
But just to keep as much of the history and attribution as I can, here's the dead links I have for Mike: http://teach.beaverton.k12.or.us/~mike_caputo and for the article: octm.org/TOMT.html
I've seen a number of great videos on this in the past ten years, but none that capture quite the spirit and framing of the original love test in the way I remember it. Or maybe this is never how it originally was and I made it all up. No idea, but I had fun making this and I hope you had fun watching it :D
And an extra special Valentine's Day thanks to my Patreon patrons, whose support make this possible. Thank you Ray Sidney, Pat Devlin, David Perryman, Andew Romaner, Andrea Bi Biagio, Jodi Vezzetti, Yana Chernobilsky, David Smith, Alan Boulton, Nancy Blachman, and Caleb Wright, for your extra support!

If you want to attempt to make the thing at the end of this video (spoilers) you can, but I must say I don’t recommend it to those without a lot of experience with these kinds of things.

You may see a peek of a set of 4 truncated octahedra with one for each member of the Beatles. These came from the brilliant mind of an artist on Etsy named Tess, though she no longer seems to have a shop or a public-facing web presence. Tess, if you see this please please tell me WHAT WAS GOING THROUGH YOUR MIND WHEN YOU DECIDED BEATLES TRUNCATED OCTAHEDRA WERE A THING THAT NEEDED TO EXIST. Because you were right. So right. You give me faith that BTS Octahedra need to exist too.

Happy Pi Day, everyone. I know it's been not just a long while but also a weird while, and I'm glad to see you're still here with me.
Stay home, Pi!
This year we're doing Pi Day as a purely online event. Please feel empowered to eat a pie by yourself. We're not saying you won't get coronavirus or give it to someone else, but how often do you get the opportunity to save lives by procrastinating and delaying the inevitable? Slow the spread, wash your hands, and have opinions about mathematical constants.

Did you know that, like, while regular polyhedra have been around FOREVER (like thousands of years), regular polylinks were discovered relatively recently and are still being explored!
