Fractal surprise from complex function iteration: The movie
The movie shows the images as discussed int the earlier post “Fractal surprise from complex function iteration” for a decreasing value of the constant c. The program of the last post creates the movie frames. The movie begins with c=0.4 … Continue reading

Fractal surprise from complex function iteration: The code
// here is the program for the last post // Fractal surprise from complex function iteration // simply use it in processing 1.5 (I don’t know if it works in the new version 2.) // you can download it from … Continue reading
Fractal surprise from complex function iteration
Recently I got the inexpensive Dover reprint of Clifford A. Pickover’s book “Computers, Patterns, Chaos and Beauty”. Part of it extends topics presented in “The Armchair Universe” by Dewdney. And there are other interesting ideas in Pickover’s book. Get it, … Continue reading

How to program an ideal kaleidoscope
I have always been fascinated by kaleidoscopes. But often the mirrors were not well aligned resulting in disappointing images. Thus created a virtual kaleidoscope on the computer. Then it is easy to have perfect mirrors and to try different geometries. … Continue reading
Cellular automation on the lattice of triangles
The tessellation of triangles can easily be mapped onto the square lattice, see the figures at the left and right. Upright triangles (colored green) and upsidedown triangles (white) go into separate rows. The lines of interaction for the Von Neumann … Continue reading

The Voronio diagram of quasiperiodic tilings
In the post “Beautifying the double grid” I have shown how to get an interesting trellis by distorting the grid of a quasiperiodic tiling. Here I am showing Voronoi diagrams of the corner points of tilings, which make nice trellis … Continue reading

Doubling the semiregular tesselation of hexagons and many triangles
There is one semiregular tessellation of sixfold rotational symmetry left over which I have not yet used to create a quasiperiodic tiling of 12fold rotational symmetry. It has rings of triangles such that the hexagons do not touch each other, … Continue reading
