ReferenceFinder: Find coordinates on a piece of paper with only folds

Folding is more powerful than ruler and compass constructions. One can do cube roots, angle trisections and more.

Coincidentally enough, I had mentioned straight edge and ruler constructions in a different thread a few minutes ago

That is really cool. I wish it had an animated video to display the result, that'd be even easier to follow and therefore even more impressive.

Maybe possible with that DSL the YouTube channel 3Blue1Brown created?

I enjoy when HN surfaces out-of-the-box type stuff like this. Very cool.

“outside of the box”?

Is this brute forcing, or is there more to it?

There's more to it. Origami as a calculation tool is more powerful than compass and straight edge.

Folding could be called a superset of measuring.

Measuring could be called a special case of folding (it's an accordian fold)
