Torus knots are beautiful knots formed by wrapping a line around a torus and tying the ends together to form a loop. The resulting knot has a star-like appearance when viewed from above. The 36 examples with the least number of crossings can be seen at the Knot Atlas's page on torus knots.
In mathematics, a knot is a closed circle in a three-dimensional space that crosses itself multiple times. Since it is closed, it has no ends to tie, meaning you can't actually create such a knot. However, if you tie the ends together after you create a knot in the standard way, you will have something that is close to the mathematical description. In this post, we will explore the creation of mathematical knot sculputures using copper tubing and solid solder wire.
Did you know that you can "write" in polyhedra? I just stumbled across a $24.99 font called Divina Proportione. Created by Brazilian graphic designer Paulo W, the typeface is constructed with beautiful geometric renderings by the famous Renaissance printmaker Albrecht Dürer.
Solar Shades Looks like it's going to be another hot summer and this time of year, I always get questions about the best kind of Shades for the home! I may be a little bias in my opinion because I'm going through a more minimalist "less is more" style in my life right now. Taking the more modern design approach that is very popular right now, I wanted to talk a little about Solar Shades for the home.
You may find that granny squares lean or curve around when you are making the square. When I make my granny squares, I just keep going in the same direction without turning. You can turn if you want to make your squares appear more consistent in look, on both sides. If you have a specialty square with certain design elements, that may prevent turning. The decision will be up to you in the end.

I guess this leaked a couple days early. *edit* Looks like they just deleted the news post off the website, but I managed to save a copy (see below). Wow, such a solid lineup. You do not want to miss this! If I was only able to go to one San Francisco festival this summer and had to choose between this and Outside Lands, Treasure Island would be the easy winner. Even though The Strokes are one of my favorite bands and are headlining OL, I would choose Treasure Island because this line up is j...

Zeiss recently debuted their Compact Prime Lens set at NAB. The best part: no mount modifications or adapters necessary! Zacuto has done one better with their new DSLR Baseplate system. Previous rigs had unwanted play when using the follow focus. "Zacuto’s new DSLR Baseplate System, debuting at the NAB show in Vegas, mounts to the camera and lens using the standard 1/4 20” screw and ¼ 20 lens support, which gives you two mounting points for rock solid support to the camera & attached prim...
If you ever find yourself in the unfortunate predicament of being stranded outdoors in the snow, don't eat snow off the ground. Eating solid snow will sap your body of precious internal heat (since the heat will be used to melt the consumed ice), so it is best to melt the snow completely before drinking to stay hydrated.
For the month of April, Android maintained it's edge over Apple's iOS platform, 52.5% versus 41.4%, with Blackberry, Microsoft, and Symbian rounding out the top five (2.5%, 3.3%, and 0.2%, respectively). Due to the vast number of OEMs that manufacture Android smartphones, Apple does have a solid lead in the device market, with a dominant 41.4% market share, with Samsung, LG, Motorola, and HTC rounding out the top five (27.7%, 6.5%, 6.3%, and 5.3%, respectively). The research, compiled by comS...
We've seen the talented Diego Stocco's music from a tree and experibass. YouTube's Julian Smith now brings us something equally unusual. The combined sounds of an old Jeep Cherokee (slamming doors, pushing door locks, revving the engine, setting off the door alarm, etc) make a techno song.
Young C. Park, retired dentist of Honolulu, Hawaii, has satisfied a life long interest in model airplanes with his meticulous, incredibly detailed models of the Corsair and P-51 Mustang. Pictured below is Young Park's Corsair.
Here we are again. This time, however, it's not Britney Spears that's being uke-d, but the delightfully infamous Lady Gaga. The wicked (we-can't-help-but-look-watch-listen) Lady Gaga.
Cool cassette tape art by Atlanta based artist Brian Dettmer. From Design Boom:
Whoa, these bygone era triplets are seriously flexible. "The Ross Sisters were a trio of female sibling dancers consisting of Aggie Ross, Elmira Ross, and Maggie Ross (whose real names were Vicki, Dixie and Betsy Ross). Their public attention peaked during the 1940s, during which they were featured prominently in the 1944 film Broadway Rhythm. The sole remaining known film clip shows them performing "Solid Potato Salad", which features the sisters' amazing contortionism."

After a decent amount of downtime, one of the best indie game sites on the internet has finally relaunched! PixelProspector is a one-man gaming blog and YouTube channel devoted to the weird and beautiful world of indie games. In the first half of 2010, it received a huge boost in popularity from its video 235 Free Indie Games in 10 Minutes, a hypnotic montage of the best indie games the site had to offer at that point. And to celebrate the relaunch of the blog, which now has an improved desig...
It's been a great year for video games, kind of. Sure, the AAA release lineup has been a trainwreck and hacking has been a bigger problem than ever. But two things have happened involving the federal government that have made video games more legitimate in the United States than ever before. The Supreme Court ruling establishing that video games were the equivalent of movies and books, not porn, was the more significant decision. But in May, the National Endowment for the Arts made another si...
In a recent episode of The Big Bang Theory, character Sheldon Cooper designed a highly complicated three-person game of chess, with an odd-shaped nonagon board and two new pieces—serpent and old woman. Seemingly pioneering, in truth, three-player chess has been around since the early-1700s, with many different variations, most of which retain the basic game structure and sixteen pieces that each player controls.
Shoot-em-up games, or shmups, consist of lone or small groups of players shooting at and being shot at by hordes of colorful enemies. The genre is thought to have peaked in the mid-'90s, but recent games in the indie world may be saying otherwise. Geometry Wars and other twin-stick games kicked off the trend, but newbies Trouble Witches NEO, Outland and just-released Gatling Gears have brought some much needed originality into the modern shmup scene—making it something worth exploring again. ...

Math class got you down? We all know sixth grade mathematics is where we all start to lose it. We get frustrated with all of those numbers, try to figure it out, but ultimately flunk out or barely pass the class. Maybe the teacher just wasn't good enough to educate us, who knows, but there's no worries anymore.
The new MacBook Air from Apple may be one of the thinnest notebooks on the market, but don't let its size full you— it's a fortress, an impenetrable laptop designed to discourage user modifications, just like the Apple iPad.

Guerrilla Games' Killzone 3 (PS3) opened strong in its first week, topping the charts as the best-selling game worldwide, as well as in the Americas, beating out Bulletstorm (Xbox 360) and powerhouses like Wii Sports (Wii) and Call of Duty: Black Ops (Xbox 360). In its second week, it fell two spots worldwide, but kept its first place title in the Americas. BioWare's Dragon Age 2 is expected to dethrone it in its third week, but that doesn't mean Killzone 3 isn't a badass game to get your han...

Sitting in the dentist’s waiting room, I found I couldn’t browse the internet on my smartphone anymore. My eyes were tired from reading and there were no headphones to listen to music. There are no magazines at this dentist’s office, just an old TV playing Russian music videos ad nauseam. Mostly female Russian singers, and curiously enough they all shared similar traits: they can’t dance. They look gorgeous, but the best they could do is small movements and two slow moves at best- a huge diff...
The very basic building block of street art is the tag. Although most people find them ugly, i just think that every artist needs to start somewhere, for street artists, its the tag. Firstly the tag is basicly writing your name, or whatever name you use for your art on a wall in a simple style. (although some tags can be quite complicated) The first step of a good tag is the marker that you will use to write it with. Tags can be sharp and clean, drippy and messy, thick, thin, simple or very e...
