Le Klint makes hand folded curved lamp shades that are prtty neat. They have workshops to teach people how to do it, too.

Centigonal•7mo ago
What's great is that, if you accidentally sit on that lampshade or damaging it while moving houses, it has a second life as an IKEA KRUSNING!

colechristensen•7mo ago
Any info about the workshops? Or instructions on similar techniques?
FuriouslyAdrift•7mo ago
It's going on right now (in Copenhagen)

https://www.leklint.com/blogs/stories/3daysofdesign-2025

An old promo showing some of the techniques they use: https://www.youtube.com/watch?v=G3T_il3Qphc

Ah sadly on the wrong continent
FuriouslyAdrift•7mo ago
There's also this: https://www.normann-copenhagen.com/en/Product/Product-Collec...

Which comes as a kit you put together (keep som clear packing tape handy... it can crack if folded to hard... lol)

You might be interested in Madonna Yoder's tessellation instructions: https://training.gatheringfolds.com/garden

I bought Folding Techniques for Designers: From Sheet to Form by Paul Jackson on a whim several years ago and found it fun to work through. I think he has a new edition and some other books but I don't have any experience with them.

colechristensen•7mo ago
I bought a few origami books on impulse today, Folding Techniques for Designers was among them so that's a good validation. I've vaguely wanted to make a fancy folded paper lamp for a while and seeing this on HN crystalized that desire into at least buying a handful of books. Thanks for the reference!

In addition to being great artists, I also learned dynamic programming from this guy via his outstanding lectures: https://www.youtube.com/watch?v=tp4_UXaVyx8&list=PLJl4xQazDg...

It looks like there's a more recent series as well: https://www.youtube.com/watch?v=r4-cftqTcdI

drc500free•7mo ago
I had him as a lecturer in undergrad, and I still remember the weightlessness of his intellect. It was one thing to realize that we were the same age, but his ability to flit around different concepts was remarkable.

There were a lot of people around who felt like high performance athletes of the mind, while he was just this sort of effortless butterfly going from flower to flower.

hokumguru•7mo ago
Eric Demaine is one of the better intersections of origami and mathematics, you should also read up on Dr Robert Lang, the OG and perhaps the most famous American JPL-physicist-turned-origamist: https://langorigami.com/

On the flip side the late Eric Joisel created perhaps the most amazing curved-crease and natural folding that we’ll ever see, his works were truly amazing art: https://ericjoisel.fr/en/home/

jmspring•7mo ago
Looking at Lang's site, yes it is a super niche area, but there is a lot of self promotion - books, events, etc. I was first introduced to the general area of curved crease, etc was with David Huffman in the early 90s. He started that work in the early 70s. So, Lang proclaims to the the first, but salesmanship is important.

Eric himself reconstructs some of huffman's work - https://erikdemaine.org/papers/Huffman_Origami5/paper.pdf

It's an interesting area.

kazinator•7mo ago
> There is a surprisingly old history to curved-crease sculpture, going back to the 1920s at the Bauhaus.

That's surprisingly recent.

TheCoreh•7mo ago
These remind me of the Elliptic Curve pieces from another post on the HN front page right now (https://news.ycombinator.com/item?id=44315321) I wonder if the poster was inspired by that one to also post these here?

Anyway, these are pretty cool/unique looking! I hadn't seen curved origami like this before.

wonger_•7mo ago
Actually I was just pruning old bookmarks, and thought people would find this origami interesting. I hadn't seen the elliptic curves post -- thanks!
talkingtab•7mo ago
The force from curved folds can be used in other ways. If you score a sheet of copper in a curved line, then fold it along the score you get a twisted form. If you have some poster board handy you can use the same technique as well. Vessels!
srean•7mo ago
Curved creases aside, the fact that folding a piece of paper gives you a straight line is itself quite amazing and deep.

Even if I couldn't trust a cheap ruler, a straight edge is a piece of paper away.

ndileas•7mo ago
One of the underappreciated causes and effects of the industrial revolution is the precision that's around us all the time. To make that piece of paper required thousands of precision surfaces, rollers, etc.
Cerium•7mo ago
And oh how we take it for granted. I recently spent a few minutes trying to make sense of a situation where I was using a corner of a paper for a square. It turned out the piece of paper was not at all square, at least a quarter of an inch out of square!
bigiain•7mo ago
One important lesson I remember from high school woodworking class ~45 years ago - when using a set square, make your markings twice with the square flipped over in the opposite direction, so if the square isn't accurate you'll get two distinct markings - and for most wood working purposes just splitting the difference by eye will be accurate enough.
titanomachy•7mo ago
But folding any piece of paper will give you a straight line, no?
ndileas•7mo ago
Sure, this would probably work with nice handmade paper. But you won't necessarily get a clean fold with thicker or uneven paper, and depending on fiber length and distribution you might get waviness or other issues
chabska•7mo ago
traditional chinese paper making is way simpler than that, and produces quite reasonably flat papers.
boulos•7mo ago
For folks interested in folding and origami, the documentary Between the Folds was excellent. I don't know if anyone recorded a Q&A when it did the film festival circuit, but if you could find one, it'd be worth watching.

Wonderful, a nice meeting place between modern and classical art. Arguably one of the most alluring features of classical art is the complexity and intricacy of detail.
davidpfarrell•7mo ago
I don't know what I expected to see, but the site was full of ... Curved-Crease Sculptures ...

Beautiful just the same!

maomaomiumiu•7mo ago
Wow, I never realized you could create such intricate and beautiful structures with origami. This is seriously impressive work!
