At BTA, we think the super ellipse is super! We believed it to be created by Piet Hein (Danish poet and polymath) to solve a design problem for Sergels Torg traffic intersection in Stockholm, but it was actually first created by the mathematician, Gabriel Lamé, in C.19^th France.  It is the perfect combination of a rectangle and an ellipse and makes for ideal tables, such as those designed by Arne Jacobsen and Hein, made by Fritz Hansen.
