Generating 2D Metallic-Mean Quasiperiodic Tilings with NKS Substitution Rules
Requires a Wolfram Notebook System
Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.
This Demonstration shows an alternative, computationally more efficient way of generating the colored two-dimensional (2D) quasiperiodic square tilings reported in [1]. The computation of the tilings in this Demonstration is achieved by using a set of substitution rules on colored squares for the Fibonacci (or golden ratio) system based on A New Kind of Science [2, Notes. Chapter 5: Section 4].
