It's once again Monday, which means it's time to highlight some of the most recent community submissions posted to the Math Craft corkboard. I also thought we'd take a look at building a model that has appeared in numerous posts. It's the simplest of the intersecting plane modular origami sculptures: The WXYZ Intersecting Planes model.
My first attempt with the sonobe unit! I'm now addicted. I'll be spending the holiday folding. Instructions here.

Undo all the screws on the laser assembly and remove the unit containing the laser diode. Now cut around the unit with a hack saw to get the di...
I wondered how silly you could get with sonobe, and had a bash at a buckyball, which is a fullerene (technically a truncated isocahedron; you can see a simple model here). It's twelve pentagons—each surrounded by 5 hexagons (20 in total)—making a football shape in England or a soccer ball shape in the USA.
If you fancy yourself a nomad, check out Walking House, a mobile and modular dwelling system that is pneumatically powered, all-terrain ready. The vehicle-home crawls along at a snail's pace of 60 meters per hour, which equates to less than 1/2 a mile per hour. Akin in concept to the rolling house-on-the-go (except in the way cooler insect-like robot form), Walking House also boasts some cool eco-friendly features:

Nobody anywhere calls the sport "soccer". But here we are, the only ones in South Africa that do not call it some variation on foot and ball. And of course, if you've pondered this before, you are probably equally befuddled that the game we call football is not even played with one's foot in the first place. American football ought to be called handball...
Hi everyone This is something that I should've done the first day but hey...better later than never right?
Ghost chiles. They're the hottest chili peppers known to man, and they come from India. They're rated at over one million Scoville units. The typical jalapeño pepper only has between 2500 and 6000 Scoville units. You don't need liquor to get messed up on these jello shots!

Math Craft admin Cory Poole provided quite a few recipes for sonobe models in his blog, and I followed one to make the pentakis dodecahedron here.
A century ago there wasn't much life available for quadriplegic people. Handicap accessibility was barely even a concept, and lacking medical technology kept any semblance of independence out of reach. Today those unfortunate enough to be paralyzed from the neck down have brighter prospects, but are still unable to participate in many activities. Video games are a great option for those who do not have the use of their legs, but for quadriplegics, the use of a standard controller is not an op...
