It’s a book of step by step drawing instructions. All you need is a ruler, compass, pencil and pen. While the geometry behind theses patterns is enormously sophisticated, actually drawing out the shapes is surprisingly easy and relaxing. It’s also a fun and painless lesson in geometry, especially for those of us not inclined towards math..
From 1966, René Jodoin's beautiful minimalist animation of a geometric ballet, "Notes on a Triangle." Jodoin, who died earlier this year, was founder of the National Film Board of Canada's animation studio. "Note on a Triangle" was only one of several films meant as an introduction to geometric forms. See more here.
Tentacles made of cubes reach for you from within the watery abyss. "You're not supposed to be here," an unseen being informs you as you descend into the first level of the game Euclidean. Deep sea creatures made of shapes swarm, pulse and strain around you—and soon, they notice you. "Everything here will kill you," the voice intones a few moments later. Read the rest
Let the People Draw the Lines Act, a bill introduced by Alan Lowenthal (D-CA), would appoint panels of independent experts to adjust electoral district boundaries in an attempt to remove the "safe seats" created through gerrymandering, by which electoral districts are torturously redrawn to include as many voters likely to keep the incumbent in and to exclude everyone else. As Wonkblog explains, the bill is a long-shot, but it's also a shining example of the kind of legislation that fights corruption and creates a climate of real representative democracy. The fact that this bill is wildly unlikely to pass doesn't make it laughable: it makes Congress irredeemable. Read the rest
Vi Hart, the Internet's favorite manic vlogging mathematician, has released a new video in which she teams up with math artists Andrea Hawksley and Gwen Fisher, and Gwen's sister Ruth of Sweets by Ruth. The four of them bake satisfyingly precise and geometric gingerbread polygons, then build up a variety of astounding three dimensional forms by piecing them together with icing. The video is both hunger-inspiring and brain-inspiring, and is likely to be the best thing you watch this week.
In the Boing Boing Flickr Pool the fractal-obsessed Fdecomite posts the latest iteration in a series of experiments with tessellated, Escher cookie-cutters. Bake-time expansion creates irregularities that lead to a chewy (literally) series of interlock-imperfections, which give old MC's classic a bio-organic air that rather invigorates it.
You can 3D print interlocking lizard cutters with a free model from Thingiverse. Fdecomite, if you're reading this, please post in the comments with a link to the cookie cutters you used here!
Update: From the comments, Fdecomite writes, "Hi, those are cookie cutters I made from aluminium foil.I also made some 3D printed Escher cookie cutters you can find in my Shapeways shop.
Here's glassblower Alan Bennett's astounding triple-nested Klein bottle, a beautiful thing:
A single surface model made by Alan Bennett in Bedford, United Kingdom. It consists of three Klein bottles set inside each other to produce, when cut, three pairs of single-twist Mobius strips. A Klein bottle has no edges, no outside or inside and cannot be properly constructed in three dimensions.
