Why these tilings are not periodic

Often, you can put together two periodic patterns of different length and you get a new pattern, which is periodic too. The length of the period of the joint pattern is the least common multiple of the period lengths of … Continue reading

Another variation on the Amman-Beenker tiling

Trying to get something new I used a grid of greater squares of length L=sqrt(2.) and a distance of 1 between their centers. This makes overlapping squares. Using two such grids as before (see “An easy way to quasiperiodic tilings“) … Continue reading

Another tiling of eight-fold rotational symmetry

I am using the same basic method as for the Amman-Beenker tiling, see my post “How to find these corner points of the┬átiles“, but now with smaller squares. The distance between the centers of the squares remains equal to 1, … Continue reading

Iteration of rhombs

We had good weather the last days and I enjoyed myself in the garden – weeding and admiring the nice tulips. I also found a nice iterative method to draw a tiling, which I will share with you now. It … Continue reading

Twofold color symmetry in translation

I was a bit disappointed by results of the twofold color rotational symmetry shown in the previous post. Thus I was searching further and found something more interesting. In the earlier post “How to find these corner points of the … Continue reading

Twofold color symmetry in rotation

Thinking of a checkerboard I wanted to do something similar with quasiperiodic tilings. The checkerboard is a square grid with two colors. A rotation by 90 degrees around a corner exchanges the colors, but else the board remains the same. … Continue reading

The basic Amman-Beenker tiling

With the details presented in the earlier posts we can easily get large parts of this tiling. I have tried to choose colors, which are not too contrasting and too hard on the eyes: We see that small patterns are … Continue reading
