I know that it has been very stressful for me and for most people that I have been in any level of contact with (which, since the start of the pandemic has been markedly less for all of my friends…I’m sorry that I have been missing from your lives – I still like you and want to be your friend!). Since humor can be an effective way to reduce stress, I hope that this particular project makes you smile. A recent project of mine that I will be presenting at the 2022 Bridges Math Art conference is all about mathematical puns. Puns are a good way to introduce complicated concepts in a non-intimidating manner. I have previously used them in various math art projects including the hyperbolic airplane skirt and the parrotohedron . The Hyperbolic Airplane Skirt The Parrotahedron Today, I am sharing some visual math puns created using stuffed (polyester-filled) animals. The resulting sculptural poly-fill-hedra are simultaneously attractive art pieces and entertaining math puns. I write quite a lot more about these creations in my Bridges short paper, which I will link to here when it is officially published later this year. The dodocahedron. 12 stuffed dodos arranged into a rhombic dodecahedral shape. The Otterhedron, a -hedron made out of eight (octo) otters. The Tetrahedron, made out of four (tetra) neon tetras. Posted on October 20, 2018 Celebration of Mind 2018 A few years ago, I wrote about participating in a Celebration of Mind event at Stanford. For those that need a reminder, The Celebration of Mind (CoM) is like a series of mini- Gathering for Gardner ‘s that happens all over the world around the anniversary of Martin Gardner’s birth. This year, I am pleased to once again be presenting at the Stanford Celebration of Mind today. I will be talking about visual cryptography and doing a re-hash of the business card origami workshop. If G4G has always looked like fun to you but you haven’t been able to go, I really encourage you to attend a Celebration of Mind. You can find similar events in your area, you can search for one on the official CoM page . Posted on November 30, 2017 November 30, 2017 Twelve Card Assembly for G4G12 My gift for Gathering For Gardner 12 was a set of 12 specially marked business cards that can be used to assemble a rhombicuboctahedron. The final construction looks like this: Apologies for the cracking when folded – I’ve never purchased business cards before and wasn’t clear about what options you needed to choose to get optimal for folding” cards. I first came up with this design a few years ago after I was handed a large pile of old business cards and gave myself the challenge of creating modular origami models of all of the Archimedean solids. As I noted in my post at the time , I wouldn’t be surprised if some (or even all) of these designs were examples of parallel invention, but I haven’t seen any of them elsewhere as yet, and I certainly had a fun time coming up with and building them, which is probably the important part”. It is possible to put this together without tape or glue, but it isn’t super easy. You may find it easier to add temporary or permanent tape as you go if you don’t mind cheating”. If you want to treat this construction as a puzzle, you should probably stop reading here. —————————————————————————- How to make your own business card rhombicuboctahedron Fold all 12 cards as indicated. (If you want to use unmarked cards, see folding directions at bottom) Groups of three cards go together like this Groups of four cards go together like this If you are trying to make this without tape or glue assistance, I recommend starting with a group of four cards held in your non-dominant hand Add cards around as in the next several images The last piece is the most difficult to add (you might have to force it a bit), but the entire structure should stay together once it has been added Don’t forget to put your pieces together in a nice color scheme! —————————————————————————————- Folding modules from arbitrary cards (Pictorial Instructions) These instructions show the easy way to fold modules. These modules are not centered, but the technique for centering the module if necessary to match with the card design should be straightforward. Posted on August 7, 2015 August 7, 2015 Hypernom – a 4D VR Game Hypernom is a 4D VR game that I’ve been working on with Vi Hart, Henry Segerman, and Marc ten Bosch. We’ve already talked about it on the eleVR blog . You can see the code on Github , read about the math behind the game in our paper , and see our presentation about it at Bridges 2015 in flat and spherical video … amongst other things . So I thought I would try something a bit different in my blog post… In which I explain our new game using only the ten hundred most used words. I work in a group that makes things for the pretend world that you wear on your head. We just made a game where you eat four-world things, one three-world thing at a time. My favorite thing to eat is made up of my favorite three-world thing. My favorite thing in the three-world is made from ten and two faces with five sides each that are put together. My favorite three-world thing is like a different three-world thing with twenty faces with three sides each that are put together. The points of my thing are like the faces of the other thing and the faces of my thing are like the points of the other thing. Both things have ten times six edges and share a group with 10 times six times two parts. Notice that 10 times six times two is also five times (ten and two) times two and three times twenty times two. If you get a hundred and twenty of my favorite three-world things put together then you have another of my favorite things. It does not fit in the three-world and instead lives in the four world. In the fun game that we wrote, you can eat all hundred and twenty of my favorite three world things by moving your head around. Go try it out now! Posted on August 6, 2015 August 6, 2015 Bridges Math Art 2015 Yuri Vishnevsky, Kelly Delp, Katie, and I make a human cube at Bridges 2015 Conference season is exhausting, so I’m very selective about which conferences I attend. Bridges Math Art is definitely one of my favorites and has a solid spot on my attend” list every year. The 2015 conference just ended, and was as amazing and exhausting as ever. This year I presented a workshop on Fibonacci Lemonade (and other mathy layered lemonade variants). Even though Bridges is all about the junctions between math and art, the art of cooking is rarely represented. The Fibonacci Lemonade workshop diversified the conference a bit with some delicious summer math fun. You can find the full paper on the Bridges archive .

We showed this in the art exhibit and also had a paper and presentation on some of the math behind the project:Hypernom: Mapping VR Headset Orientation to S3 .

Look out for upcoming blog posts about these pieces – they deserve to have more said about them than what I can fit in one...
