Straight lines have rulers, circles have a compass and angles have a protractor or set squares, but I don’t think I’ve ever seen a tool to help draw an ellipse on paper. The Ellipser is an innovative tool that takes into consideration the exact definition of the geometric term and is probably first of its kind.
An ellipse is 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.
