Here is a link to the actual paper. The original post asks for a subscription to see the paper.

edit: Grammar.

This link is a better intro than the linked abstract (contains a gif explaining the concept) https://m.phys.org/news/2019-08-mathematical-framework-sheet...

Slightly better. The text promises "allow it to morph into 3D shapes", whereas the gifs only show fairly trivial 2D morphing. What one would imagine is "take a sheet of paper and turn it into a 3D flower", but what we get is "take a sheet of paper and turn it into a deformed grid".

Ok, we've changed to that from https://www.nature.com/articles/s41563-019-0452-y. Thanks!

To add, we discussed this at work this week, and someone tried cutting the example on our laser printer. Broke when trying to expand it, though.

What material?
