This is how production designer Herman Zimmerman describes the philosophy of how Cardassians engineered their space stations and computer interfaces. The typical Cardassian interface consists of three main buttons - primary, secondary and tertiary. When combined, they form a rather complicated shape, which some call the “bear claw”. The buttons can be rotated in any degree to form an elliptical shape and to fit different designs of Cardassian consoles. Acknowledgment buttons are usually placed on top or on the sides of the elliptical shape to complete the whole interface.
