Longtime friend of the Aperiodical, artist, mathematician and #BigMathOff semifinalist Edmund Harriss has come up with a new puzzle/toy/exploration set, developing his Curvahedra system. We asked him to explain the maths behind it in this guest post.
Curvahedra is a flexible system of connectors that can make all sorts of different things, combining puzzles (and self-created puzzles) with art. You can get your own to play with, explore, prepare for Christmas (they make great decorations, wreaths and presents) at our online store, and get 15% off with the discount code APERIODICAL.
As this is the Aperiodical, you might be most interested in how it can be used to explore mathematics. In the big math off I talked about the basic ideas behind the system, Gauss’ famous Theorema Egregium and Gauss-Bonnet theorems. A really simple version of this comes from just considering triangles, that can be built up to make this:
Spanish independent publisher Kronecker Wallis is making a new edition of Isaac Newton’s Principia Mathematicia, using a Kickstarter campaign to fund the initial print run. Here’s their video:
It looks like it’ll be a fairly pretty object, and they’ve put a lot of time and thought into choosing the paper, fonts and layout. Their Kickstarter runs for around another 24 hours, and a pledge of €45 or more will secure you a copy of the finished article.

Edmund Harriss is a very good friend of the Aperiodical, and a mathematical artist of quite some renown. His latest project is CURVAHEDRA, a system of bendable boomerang-like pieces which join together to make all sorts of geometrical structures.
Here’s something fun you might want to spend some money on: a poster of the Mandelbrot set, in the style of an old-fashioned navigation chart.
The Kickstarter has already racked up many multiples of the original funding goal with three weeks still to go, so it’s at the “effectively a pre-order” stage. The posters start at \$26.

Samuel Hansen’s Relatively Prime has now published all episodes of the second season, available at relprime.com, and the Kickstarter for Season 3 is now live. In fact, it’s so live it’s almost run its course: the third season will only be funded if at least $24,000 is pledged by Saturday 12th March 2016 at 4am GMT. At the time of writing, as I just pledged my support, the project is 30% backed.
Consider supporting this third season of stories from the mathematical domain! You can watch a video of animated Samuel telling you about the project, listen to Samuel speaking about why you should support this, or read an interview Samuel did about Relatively Prime with Shecky Riemann at Math-Frolic. To drum up your enthusiasm, you can listen to existing episodes or read our own Colin Beveridge’s recaps of season 2. Don’t delay too long, though – go to Kickstarter and pledge to support the project now!
If you like your accessories ‘provably unique’, check out this mathematically interesting Kickstarter project – KnitYak, aka Fabienne Serriere, is going to generate some knitting patterns for scarves algorithmically, so no two scarves will be the same. They’ve hacked a knitting machine to use cellular automata to generate unique black-and-white patterns, which will be knitted in merino wool using a Jacquard (double) knit, resulting in lovely well-finished pieces by the sound of things (although the scarves start from $150, so you’d expect something pretty nice).
Check out the video below, and consider chucking some money on the KnitYak Kickstarter page.

Here’s a new product vying to knock the set square off its throne as Least Useful Tool in the Pencil Case.
CoordiMate is a rubber stamp which prints a teeny tiny set of axes. It’s supposed to help you with your homework.
… for the week or two that you spend learning how to graph functions.
It’s currently the subject of a Kickstarter hoping to raise $25,000 so it can go into full production. Just watch this pitch video.
