08-07. Cuprite #2.
A cuprite turning into a gyroid.
A gyroid is a unique geometrical form. It is a minimal surface that contains neither straight lines nor planar symmetry. The gyroid is the only known embedded triply periodic minimal surface with triple junctions. It was first mapped out by NASA scientist Alan Schoen in 1970.
Cuprite is the only mineral in nature that forms gyroids. They are often modified by other forms.
This gyroid was created with a small mathematical visualization utility called 3D-XplorMath.
