**Quantum register.** A model used for illustration in my papers (implemented earlier with POV-Ray and redone with Blender now). Register is in initial state and Blender *array modifier* makes file smaller. The same modifier also may [rotate elements of design](https://skfb.ly/Q6TX). For register with [less regular state](https://skfb.ly/Q6In) blender file is bigger, because array modifier is not used. Yet another example uses 2D array modifiers: [2D CA register](https://skfb.ly/Q6Qz) (3.5M faces, may be too slow). See also [cylindrical CA](https://skfb.ly/QoAO) using 2D array (remeshed to make model smaller). See also [animated model](https://skfb.ly/Qq6y).
