Modular origami is a technique that can be used to build some pretty interesting and impressive models of mathematical objects. In modular origami, you combine multiple units folded from single pieces of paper into more complicated forms. The Sonobe unit is a simple example unit from modular origami that is both easy to fold and compatible for constructing a large variety of models. Below are a few models that are easy to make using this unit.
He may be the oldest person to have invented an app for Apple devices, but 84-year-old George Weiss didn't originally intend on marketing his Dabble word game to the mobile crowd. He first came up Dabble back in 1958 when he was just 31. “A lot has changed since 1958, but people still love a good game,” said Weiss on his introduction into the iTunes App Store last month.
hi everyone, i have been teaching myself to crochet for a while now but when i come accros something i dont understand i get discouraged...im using a book n it says that this is an easy pattern. it tells meat the end of a row to miss a ch and turn...im doing this and my work is getting smaller and smaller like a pyramid...pls help me and tell me what i am doing wrong...thank u and i have learn alot from this site.
Hello World! Just a quick idea,
Giveaway Tuesdays has officially ended! But don't sweat it, WonderHowTo has another World that's taken its place. Every Tuesday, Phone Snap! invites you to show off your cell phone photography skills.
It's an ambitious How-To project to say the least, or more specifically, an over-the-top political art installation by San Francisco artist Brian Goggin. You may have previously heard of Goggin for his "Defenestration" project—an installation of "frozen" furniture, being tossed mid-air from a San Francisco apartment building. But Goggin's latest project sounds significantly more challenging to execute, considering the elaborate game plan involved:
Sick of the same boring, holiday-printed, gift wrapping paper for packaging your presents? Using spare cardboard, make a pyramid-shaped gift box for your unusually-shaped item. Or, transform your spare empty cereal boxes into fancy custom-made gift boxes.
This three dimensional Sierpinski tetrahedral structure was created with a lot of help from my Year 10, 12 and 13 classes. It is inspired by the Sierpinski triangle fractal.
Thanks to the advent of smartphones and mobile apps, Scrabble has spread like wildfire across the globe, whether it be Scrabble or one of its many popular word game spinoffs, such as Words with Friends, WordWise and Kalimat.
Last time we took a look at some of the creatures of the pond, including the dragonfly nymph. Today, we examine the all-grown-up dragonflies in the field you are used to seeing on summer days! Dragonflies are not dangerous, but the extra large ones can bite you something fierce if you handle them wrong.
Last post, the Sonobe unit was introduced as a way to use multiple copies of a simply folded piece of paper to make geometric objects. In this post, we are going to explore that concept further by making two more geometric models. The first is the truncated icosahedron, which is a common stitching pattern for a soccer ball. The second was supposed to be the pentakis dodecahedron, but through systematic errors last night, I actually built a different model based off of the rhombic triacontahed...
When you don't have anyone to play with in the flesh, nothing beats a round of competitive online Scrabble. If you're constantly on the move, the Scrabble app developed by Electronic Arts (EA) for Android and iOS mobile devices is probably your favorite way to play. But let's face it—if you love Scrabble, you probably love all types of word games, and if you're on the hunt for that next fun and challenging logological mobile game, I've got a few suggestions for you...
