we have a ruler to draw a line, a compass to draw a circle, and a protractor to measure an angle. however, we have never had any tool to draw an ellipse. giha woo has a solution to this problem in the form of ‘ellipser.’  the definition of a circle is a group of points located the same distance from a given location called the center. however, an ellipse is more geometrically complex. it is described as a curve on a plane surrounding two focal points, such that a straight line drawn from one of the focal points to any point on the curve and then back to the other focal point has the same length for every point on the curve.

after discovering these rules, woo was able to create an instrument thats meets the mathematical requirements for the formation of the shapes. from the designer: ‘the advent of computer graphics resolved this problem so easily. however, the fact that there has never been an analog method to draw an ellipse became a stimulant to a designer like me. I wanted to know the definition of an ellipse before contemplating on a way to draw an ellipse. it seems that if I know the definition, then I will be able to find out the rules. then, if I know the rules, I believe that I will be able to know a method. lastly, if I know the method, then I will be able to create a tool.’
