In this video for Wired, physicist and origami master Robert J. Lang demonstrates the 11 increasingly complex levels of origami. How all the legs and antennae and other small features are designed at the more complex levels is fascinating.

Check out these elaborate and colorfully decorated origami creations by paper artist Cristian Marianciuc.



To create these intricate artworks, Marianciuc folds traditional origami cranes and then adorns them with hand-cut paper and other materials. Some of his creations are available in his Etsy shop. (via @imperica)

This origami simulator built by Amanda Ghassaei is really cool. The simulator lets you explore how different origami patterns are constructed by moving & rotating them around on the screen and folding & unfolding them. You can even import and export your own patterns. (via kelli anderson)

Origami artist Ross Symons makes tiny origami creations and posts them to his Instagram account, White on Rice. The account became pretty popular and Symons was able to turn his hobby into his full-time job doing installations, exhibitions, and social media campaigns featuring origami.
Over the weekend, Symons' art was featured on Noticing, kottke.org's free weekly newsletter. You can read the full issue here: Lobsters Considered, Superteens Against the Autocracy, The Mister Rogers Fan Club or subscribe here to have it land in your inbox each week.

Believe it or not, I used to be a mathematician. And stupidly, I didn't apply myself to applied math, stuff that uses computers and makes money. I was interested in 1) formal logic 2) the history of mathematics 3) the foundations of geometry, all of which quickly routed me into philosophy, i.e., obscurity.
But it does mean that I remain stupidly interested in things like ruler-and-compass constructions, axioms for foldable geometries, and the difference between Euclidean and non-Euclidean spaces. Folding is especially interesting because it's tactile, it doesn't require tools, and it sort of requires you to mentally balance the idea of the paper as representative of the geometric plane AND paper as the tool you use to inscribe that plane... oh, forget it. Let me just show you this cool GIF:
I'm not sure how this fits into foldable geometries exactly since it imagines an infinite procedure, and geometric constructions are typically constrained to be finite. But still. It's really cool to look at, play with, and think about.

This folding measuring spoon on Kickstarter is clever as hell. Polygons lays flat in a drawer and, depending on how you pick it up, folds into four different volumes.
Premarked areas on both spoon sizes (tablespoon and teaspoon) let you know where to pick up from to measure the volume required for your recipe. Practicality and simplicity at its finest.
The spoons come in two sizes (the smaller measures teaspoons and the larger one tablespoons), they're marked with US and metric measurements, you can flatten it to easily scrape every last bit of stuff into the bowl, and it doubles as a knife when flat as well. (via colossal)
Update: Hmm, it looks like Polygons needs a little more work to be a fully functional product. (thx, mac)

This is the origami alphabet:

When a piece of paper is folded according to these directions, a 3-D extrusion of the alphabet will result. The alphabet's creators have also devised an alphabet made by the hinged dissection of a square.

Between the Folds is a documentary about people who really really like origami.
Between the Folds chronicles the stories of ten fine artists and intrepid theoretical scientists who have abandoned careers and scoffed at hard-earned graduate degrees — all to forge unconventional lives as modern-day paperfolders.
Kevin Kelly gave it a rave review on True Films and it's showing on PBS's Independent Lens this month.

Next year, the Japanese space agency is planning to throw paper airplanes (aka origami space shuttles) from the International Space Station with the hope that they will make it to earth intact.
It is yet to be decided whether Wakata himself will throw the paper planes or whether he will use the space station's robotic arm.
The planes are made from sugar cane fiber paper treated to withstand high temperatures and strong winds. (via waxy no idea where I got this)
Update: The launch of the origami planes has been scrubbed. (thx, edieraye)
