Penrose Substitution

This sketch uses a tile substitution method for constructing highly ordered aperiodic tilings. Each construction is made entirely from just two basic shapes. The shapes are triangles. Commonly called the ‘half-kite’ and ‘half-dart’ , they are derived from the pentagon and described in depth by Roger Penrose. There are two substitution rules for each triangle.…

Blended Tris

Another algorithm in the Blended Arcs and Blended Ends modality. Recursive regions are filled this time with triangles, eventually becoming tiny villages of computational gnomes. Programmed in ProcessingBy Jared S TarbellIn Albuquerque, New Mexico, USAAround 11:36am November 20, 2019

Blended Arcs

Subdivided regions draw partially completed circles as pie sliced arcs. When stacks of arcs overlap each other, the machine inverts both layers, multiplies them, and then inverts that result. The color then tends to always get brighter, towards white. Blend mode is built into Processing. This is an derivation of Blended Ends. Programmed in ProcessingBy…

Blended Ends

A randomly subdivided quad tree fills the voids with blended lines. Each line is drawn from top left to bottom right, with an offset midpoint and thick colorful halo. The subdivision process builds complexity until resulting regions reach a minimum area. Images are displayed in reverse order of creation. Programmed in ProcessingBy Jared S TarbellIn…
