Pictures and movies of random lozenge tilings
2016/08/20
In Spring 2015 and Summer 2016 I used the Python and Mathematica
as
briefly
described here
to produce a number of pictures and “movies” of random lozenge tilings.
Some of these pictures even appeared at an art exhibition at Harvard’s Radcliffe Institute accompanying Alexei Borodin’s fellowship.
These pictures and “movies” of random tilings are collected in this post.
Dear colleagues:
Feel free to use these pictures to illustrate your research in talks and papers, with attribution (CC BY-SA 4.0). Some of the images are available in very high resolution upon request.
