The humble cone contains the answers to fundamental questions about the universe. But not this one, its just pixels on the screen. What is mildly interesting about this cone is the way it is generated - a 2D polyline forms the bottom side and hypotenuse of a right-handed triangle in the X-Y plane. This flat shape is then "extruded" into three dimensions by rotating around the Y axis to generate the cone. Another shape which is generated by rotation and scaling extrusions in multiple dimensions can be seen here: https://github.com/rm-hull/wireframes/blob/master/doc/gallery/weird-swirly-thing.stl
