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

This duo must have the most fun job in all academia.

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

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/

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

That's surprisingly recent.

Very cool math and technique that results in... shockingly little expression. As art qua art, the resulting forms here are utterly bereft of any feeling of artistic purpose or intensity. "Art for math's sake" I suppose?

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.

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!

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.
