Bridges 2018 Stockholm
I have been at the Bridges 2018 conference in Stockholm to present my work on kaleidoscopes. My paper “Kaleidoscopes for NonEuclidean Space” has more details than this blog and is more coherent. The Bridges Organization, which promotes connections between mathematics … Continue reading
Rotations, mirrorsymmetry and the scalar product
In the last post we have seen that scalar products between a pixel’s position in the output image and certain vectors e define periodic and quasiperiodic designs. We want symmetric images and thus we have to see how the scalar product changes … Continue reading

How to calculate the corner points and the projection method
Again something for the more mathematically minded. I am discussing here some important details on the earlier post “A tiling of 12fold rotational symmetry …” . Actually, these calculations are similar as in the earlier post “How to find these … Continue reading
Exhibition of the selfsimilarity of the tiling
In the last post, I claimed that the tiling one gets from two hexagongrids is selfsimilar. But this is not clear from the image I have shown because it has only about 2000 tiles. This is not enough. Just look … Continue reading

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 tiling of eightfold rotational symmetry
I am using the same basic method as for the AmmanBeenker tiling, see my post “How to find these corner points of the tiles“, but now with smaller squares. The distance between the centers of the squares remains equal to 1, … Continue reading

The basic AmmanBeenker 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
