    Here is how you can fold a piece of paper into an ellipse: 1) Cut a circle from a regular piece of paper 2) Draw a dot inside the paper circle 3) Fold it so that the circumference falls on that point 4) Repeat this procedure using random foldspic.twitter.com/T4s3hUcIY9

        The sum of lengths of two segments (CA and AB') joining a point (A) on an ellipse to its foci is constant (radius of the circle here). The locus of all A s will thus form an ellipse will C and B' as it's foci.pic.twitter.com/1840277O9Q

        Nice. Wonder if other objects (rectangle, triangle, etc) have similar/comparable properties.
