According to Wikipedia, The term “circle” may be used interchangeably to refer to either the boundary of the figure or to the whole figure including its interior; in strict technical usage, the circle is only the boundary and the whole figure is called a disk. A disk is said to be closed if it contains the circle that constitutes its boundary, and open if it does not.

Open Disk by Daphna Laurens is literally an illuminated disk. The design can be seen as a celebration or even a glorification of the shape; one that designers owe a lot to. Since no secondary circle encloses the disk, it can be understood as an open entity. This mathematical reality inspired the design duo on a conceptual level, as an expression of openness; the positive impact of good things in life.
