Welcome to the (Euclidian) egg project. Use geometric construction based on compass and ruler methods to create egg shapes and other similar mathematical structures. These ideas are based partly on some activities from www.1000problems.com and partly from the book "Mathographics" by Robert Dixon. All constructions use interactive geometry from C.a.R.
