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

Lovely.

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

It's a strange coincidence that I commented about straight edge and ruler constructions in a different thread.

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.

Folding could be called a superset of measuring.

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

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

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